Carl, No problem with what you or Bob said. My issue as an engine installer was to get the max output of an engine up to its rated power for the application. Having a little extra is good. But when you can only use 75% of rated power because you can't load them enough, one is wasting weight and powe...

Bruce

One of the 31's I did was 370. Don't remember fuel burn, but top end was 36 knots. Biggest issue was putting the power to the wheels and loading the engines with the limited prop diameter without pockets. Prop tweaking is a must. I also did a set of QSB but cut the hull for pockets to swing a bigger...

Bruce

I think Faria makes one set up for pulses from a flywheel.

Bruce

I don't recomend pertronix. Any fuel pump pressure guage for reading low fuel pressure will have push on hose connection. Make sure a clamp is used on those connections. You can buy a 10 psi guage with threads and create a more solid connection on ebay cheap. Get a pipe t and install in line feeding...

Well I guess the brainwashing of America's youth into college because working with your hands is somehow beneath human dignity, has caused a shortage of techs.

I'm sorry to hear you can't find somebody. I really enjoyed it for 29 years. Was able to help a lot of people out.

Bruce

Buzz, Have you walked the docks and inquired with gas boats who they use? Also the manufacturer of the engines Merc, Crusader, etc should have a listing of dealers in the area. Check with Anchorage marina on Atlantic beach. I believe the owner is still Jim Bailey who used to own Buddy Boy, he is a h...

Bruce

Congrats Carl.

Many hours of enjoyment for you and the family.

As one who has serviced both gas and diesel let me offer an opinion. First a B series cummins is about as simple an engine as it comes. All engines gas or diesel need air, fuel and an ignition source. A B series cummins doesn't need any electrical wiring other than the starter motor. People over com...

Bruce

On both they are parallel. I don't know how your system is set up but the majority of 1, 2, both batteries is the battery you are using is being charged. So on both, both are being charged. Unless you have the altenator going out into an isolator that splits the charge to both batteries regardless o...

Bruce

Back when I was a yanmar dealer and the 4lh and 6lp engines went away due to emissions, we were not allowed to sell those engines in the US anymore. I was allowed to buy engines, import them to use on foreign flagged vessels. I'm not sure if you are going to keep your boat foreign flagged or registe...

Bruce

Hueso,

No you can't.

Those 170 would not be good for 31.

Bruce

Ring up the Coasties, they should know.

Bruce

One of those systems does give fuel burn in mpg with a GPS speedo, I thought it was fast. Too many things to remember at an old age.

Bruce

I've seen, installed and serviced every after market TB and multiport injection system on the market. Fast is one of the better ones but some advice. You only get get one O2 sensor. Every factory system uses 2 to monitor both sides which is much more tunable and results in better AF ratio adjustment...

Bruce

They have a new web site, https://floscaninc.com/ , sya they are under new management and Joe is still listed as a contact.

What gas injection do you have factory, aftermarket return line to tank or re circulation?

Bruce

Seals get old and dry out or the internal coil spring around the lip of the seal breaks and the seal lip is not as tight on the output shaft. A slide hammer on the shaft still attached to trans output shaft shocks and that internal lip spring can come off. Might want to change seal while out of the ...

Bruce

Use tef gel on all bolts. Tighten pinch bolts first. There should be a partial groove in the shaft to align flange with shaft.

I used steel bolts and tef gel'd them.

Mikey,
Familiar with the 30 Bertram, a few came thru the shop.
Those engines should turn 4400 wot.

You don't say if you have a cup or not.

Have you checked physically to make sure throttles mechanically opening all the way open? Your speed seems low vs rpm.

Bruce

I talked to Ricky and feel the tachs are reading off by 2k.

He has some other issues that when he gets back to the boat next week he'll call me and I'll go thru some things with him.

One thing that is overlooked is the drive plate on the flywheel.

Most all gas use springs to take the torque hit. They wear and can create a clunk.

Many flywheel housings have a rubber plug at top. If so remove at see if the springs are loose with a screw driver. Springs should be tight.

Bruce

Ricky,
Call me sent my number to your pm.

Bruce

Guys,
A bunch have already responded and things are okay.

Save your donation and take the family out to eat when this insane lock down lifts.

I really appreciate it guys.

Bruce

Carl,
You will not be able to feed enough water to the water pump to keep it from starving itself out of the water at anything above idle. A garden hose won't do it, it will suck a 5 gallon bucket dry before you look at the gauge.

My father who was an engineer for FORD and traveled frequently to various Ford plants for production issues once told me when I asked when I tore my first car apart at 13 about doing things the correct way and he said, there is a balance between costs, doing it safely and making it bullet proof.

There are a number of freeware programs, low cost programs and even draw programs that contain electrical symbols. Some I've used were simple, others required more time than I was willing to spend on it. If your doing it for yourself your time is for you. If you do it for a client you don't want to ...

I sat in a bunch before I found one that fit me comfortable. Looked at one's that cost 3k and below and settled on the Bass Pro ascend.

Bruce

Carl,
Met a bunch of marine mechanics thru dealership training and seminars and a good portion of em didn't give a rats ass about boats or boating it was just a job.

Bruce

Want to get one for my fishing kayak.
Bass Pro has a Humminbird helix 5 chirp with down imaging gps gen for 299.

They also have a Lowrance hook reveal 7, 7x splitshot, 7x triple shot.

Anybody have experience with these cheap units?

Bruce

I've done the trip from key west as far north as Montauk a couple dozen times some with Pat' others alone, although not recently and not in anything faster than a 18 knot cruise so a lot of stops along the way. Only issue I found was the increase in slow speed intercoastal runs because of homes. Som...

The oil sump doesn't go to the bottom of the pan so any metallic particles that settles out of solution won't get picked up. Besides if they are circulated they go from the sump to the filter which will catch them. Next oil change have the mechanic drain oil, pull pan plug and affix a magnet to the ...

Bruce

There is no need to squeeze every drop of oil out of an engine. If your changing it on scheduled basis it's not the lubricity that your worried about its the additives. 10 or 20% of old oil left in an engine won't change anything. Out of thousands of gallons of oil I've changed over the years I neve...

I don't miss that crap at all. Although shades of it came to mind yesterday when tearing down a 283 out of a 67 numbers matching Camaro that has been sitting in a garage for 21 years partly apart. The smells of an oily bilge wafted up to my nose only to find when I pulled the pan a gelatinous rat th...

If they are 450hp JT conversions (junk and trouble) I would be wary of having them in my boat. Lots of down time for repairs. Over the years I shipped lots engines and parts to the canal for venture boaters stuck at the mercy of local repairs. Hope you have a bank line of credit equal to the stimulu...

You can use the search function and put in "yanmar 6lp props" and come up with all kinds of answers.

All ramps are closed in pbc.

Martin county closed last night, will reopen Monday morning.

Go to the building tips, Pat has articles on filling holes, hull repairs and more.

Bruce

All ramps and marinas are closed in palm beach county, only commercial fisherman are allowed out. Po Po is patroling waters.

Bruce

What yanmar are you running, 4lha?

Law enforcement rarely prints for theft unless it involves some type of bodily harm. Even if you have video from homes recording the event, doubt they would pursue it especially since you got the boat back. Might think hidden ignition kill switches. Behind galley draw is where I used to place them. ...

Carl,
You just described half of Hollywood actresses.

I'm locking this thread as it is straying from boating related in the main forum.

Feel free to open a CV thread under politics or non boat projects but let's keep the main forum related to boating topics only.

Thanks
Bruce

3208 in 325hp are good engines. Saw a lot of them in commercial boats with 20k hours or more.
Slow in 35.

Thank you for the support guys.
