There is no such thing as a silly question. Knowledge is king not only for doing a good job, but doing that job without financial waste. Been doing restoration and customization of cars for a while now, mostly domestic. Now I've switched recently to European and one thing I've noticed is the lack of...

As one who ran a whole bunch of 31 configurations, the lower helm is handy if you travel in inclement weather at slow speeds. Given the 31 bow proud ride at speed,, its very hard to see. It probably would be cheaper if you already have 3 sides bridge helm covered and your running heat, to get the 4t...

Bruce

I've seen it done on larger yachts. The premise being if the intake gets clogged really bad, eel grass etc, the primary intake can be closed and secondary valve to tie in the other intake is opened. This was mainly done for slow speed docking ability to maintain control when you had super structure ...

Bruce

Many vhf radios have a hail or pa function. Install cockpit spkr and wala.

Bruce

Can you run a seam of caulk on the top joint all the way around?

Bruce

At least it will be on large Yachts who will employ one or two engineers that will be trained by Man.

Not sure about Europe, but the US is sadly lacking in qualified service personel to service those technologies.

Bruce

Apparently the severe freeze they had this past winter shut down plants across Texas for one. The other issue is makers of anti freeze are being caught up in environmental issues and looking to make more friendly coolant and of course C19 is being blamed also. Welcome to the latest shortage of manuf...

Bruce

Who repowers and redesigns a boats power set up without making sure it is going to work? Perhaps someone with too much money and no common sense. Actualy its three things. Too much money with junior engineer types. Too little money to do a proper job. Or doing just enough to make it a utilitarian v...

Bruce

Rocky,
Marine power makes a 5.3.

Bruce

If Raybo is doing it, it will be done correctly.

Bruce

I changed this to a sticky and modded the title to let everyone know Scott passed so they can respond.

Those are the typical gas engine supports. They need to be unbolted and removed, saved for the wood or thrown out.
Here is the link to new engine beds for diesel conversion not only for strength but the ability to service the sides of engines.

Bruce

If your sure rpm is correct, 3900 is where Yanmar told us dealers to run them wot. Bertram stringers usually were roving over wood. Wood rotted out under most time. Are you talking about engine support stringers? They should have been redone when repowered. Or are they using old gas stringers cut do...

Bruce

I guess you don't dive much ...and PLEASE Don't tell the Government that as we'll soon have an air Tax. We already pay an air tax in the way of emission standards on fuel and increasing costs for internal combustion engines. Not to mention freons and all other costs associated with ozone layer depl...

Bruce

I would like to ask if I am hurting or helping the longevity of my 6Lp's? I have a 70 model Flybridge cruiser with Yanmar 315 HP 6lp's. I will put about 125 to 150 hours this year with about 75 % of those hours "cruising". I do not fish so I do not have a lot of idle time (which I assume would buil...

Bruce

I heard a comment about side induction boxes allowing water intrusion. If designed and installed correctly, that is not going to happen. For those that pull the air directly from the cockpit above the deck, engine noise is going to be a factor and will erase time and money spent on engine box insula...

Bruce

Since the 42 and me are practicaly neighbors, I'd be glad to do an in person look see. Let me know.

Bruce

If CX and PB blaster isn't working, apply heat to nut with a concentrated flame. One of those butane crack torches work good, use it all the time at work. If the nut and the stud are fairly clean of rust, then the threads may be galled. If thats the case then use an impact, air or battery, to try an...

Bruce

After 29 years in the marine business the thing about buying more time never panned out for 95% of my clients. Time is a commodity that in this day and age is rare. Usually buying more time ends up costing more in the long run because no matter how much commitment one mentaly makes, it very seldom w...

Bruce

What's the hp rating?

Bruce

Don't always rely on a prop stamp to tell you what size they are.

Bruce

Yes 2:1 But like i said, the ratio is slightly different for the reverse rotation engine. Most 31 repowers using the 6LP used 2:1 gears because of the higher engine rpm. I think I did 7 or 8 31's with the LP's and 2:1 gears. I know some guys used 1.5:1 ratios, but you could still swing the proper pr...

Bruce

They are both the same hp. Engine blew cause nobody did the valve recall on those early engines. If your using zf gears, they will be slightly different ratios because of the reverse rotation. Those engines were recommended by Mastry to turn wot 3900. Engine survey should have used photo tach cause ...

Bruce

It was stored on the hard up at Hinckley with the plugs never pulled. Batteries went dead and boat filled with rain water and sat. There was a fwd bilge pump. Pat plugged the lower bilge wash thru and installed a screw in deck plate to keep water out of fwd compartment. If you hit something under wa...

Bruce

It's a shame how that boat was let go and beat down like it was. Glad Pat ain't around to see it.

Bruce

Peter, If you'd like I'll look at the surveys and give an additional opinion. I have heard Buddy Boy was let go and before Pat passed, we agonized over it cause we both put our blood, sweat and tears into that 31. For me the main mechanical feature was the Yanmar 6LY engines. They were commercial gr...

Bruce

You can still time without the shunt, just keeps the advance out.
Timing may jump without the shunt some, but you can take the lowest reading on your indicator to get base timing at idle.

Bruce

Sometimes the terminal I on the starter feeds ignition on start, trace back.

Someone also could have pulled two wires off feeding other items, electric choke, electric fuel pump, etc. Nothing should be fed from the + side of coil Back track wires to find out.

Bruce

Boy this is one event I'd like to come to, sadly can't. Spent a week every summer in St Michaels on dad's boat for 12 years. Great place back then. I wonder if it changed since last there in 74........
Have a blast.

Bruce

Changed to a sticky to keep at the top.
Lets see if we can help Bob's wife sell the boat.

Bruce

Yanmar way back when they started to power the power boat industry instead of concentrating on sail boat power, I had the unfortunate distinction of being involved in a project of repowering a power cat with 6LY diesels and bravo drives. Drives lasted less than 100 hrs each. The torque destroyed the...

Bruce

Just for checking, disconnect cable from trans lever and try movement again. I've had the selector arm/spool valve tighten up.

Also are you dual controls and if so do both cables go to engine or bridge control cables to lower controls and lower controls to engines?

Bruce

Almost all the 31's I've seen original to the factory from the rear looked like Jack Elams eyes in Cannon Ball run with shafts.
What are you talking about in degrees? Toe in at front of engines or rear?

Bruce

You would think that the minute the two pilots started to argue with weather conditions as they were, the master would have taken charge.
Seems the bridge was in a Charlie Foxtrot moment.

Bruce

Are you running one egt probe in the outlet, cause running rich can create burn in the manifold raising temps but cyl temps can be good. What about a faulty probe?

Did you try under load taking heat readings off each cylinder to see if they are with in range?

Bruce

I started with airplanes, then 29 years and hundreds of repowers and refits of boats and yachts, now I'm going on 8 years of higher end custom car building and I will tell you the one thing I have told all my customers over the years when they have voiced the same concerns as you have and that is if...

Bruce

Holy necro post Batman !!!!!!

You have to wonder about a charter operator who grabs an old, old post just to advertise if they could find fish to begin with.

I alt, control, deleted the post. Happens again, they will get the ban hammer.

Bruce

Not sure what the back ground of the writer is, as most writers have little to no life experiences in what they write, but I know Bob and certainly I could write volumes on engine life. There is no perfect answer, I've seen engines out of the crate blow up and others that receive very little mainten...

Bruce

Do you have anti syphon valves in the system?

Bruce

I've done one 31 with pockets. They were nothing like Penn Yann tunnels.

The last one was when Cummins came out with common rail QSB. I got the the first pair out of Cummins SE they were 370. Needed the pockets to turn the prop size. Boat performed excellent. I've posted pics of it in the past.

Bruce

I have two, one pretty much paint ready, the other needs some gel coat touch up.

Let me if your interested in them anyone. I don't know the value of them, so make an offer.

Bruce

You can leave them if you wish, but if you have insurance coverage you might want to check with them or read your policy as it relates to gasoline inboat boats and if they have any specific things on fuel systems. I know my business liability policy coverage excluded me from using glass or clear bow...

Bruce

There was instead of a tube to carb on early engines glass bowl for just that reason Tony.
Surprised that you still have that feature after all these years Peter. Most of those pumps have been replaced long ago.

Bruce

They were actually filter housings in the past with glass to see debris. Filters became hard to get and with the advent of better filter seperators like racor, people never replaced once removed. It's against the law for boat manufacturers of new boats, but not boat owners of older boats to have. Bu...

Insurance as a whole is a suckers percentage game. Was in boating biz for 29 years. Thousands of customers, can't remember anyone who lost a boat. A couple did but they were on purpose for insurance fraud. You keep your boat in good shape, chances of a loss is nill. Never carried insurance on a boat...

Bruce

You can ask whatever you want for something, depending on the demand you may or may not get it. Think of art....there is no art without money. Paintings are only worth what some collector is willing to pay. There was a time that gas 31's were going for over 100k and needed work. Paying people to do ...

One doesn't have to fire missiles or shoot bullets anymore. China, Russia, US, Israel, etc has proven warfare is just a few key strokes.
