You may want to check for slipage, plug in your info with reduction and see where your slippage falls. If excessive you may want to add some cup while reducing the pitch. But first I would find out why RPM's are off so much. Fuel restriction, clogged filter, bad wheel, stuffing box too tight.. its g...

There was a 28 by me that was donated to the Maritime Chaplins that had a pair of 502's.

Powerplants where yanked out as she was too fast and unmanuverable at low speed, or was it, the boat could not go slow enough to manuveur?

Still the age of blacksmith with propscan. Yes they check out the prop with the probes and find out what needs to be tweaked, but then they go into the back and beat the hell out of the prop and come back and check it again. It is agreat, accurate measuring tool but still need a good talented hand t...

When I bough tmine one side was 92" the other 93". Now with reduction box's I am 88"

If the boats in the water, its all gonna be wet sanding. 120 grit emery strips will work just fine. By the time you get from one end to the other the cloth will have broken down enough to give a nice polish. You could sand that shaft till your arms fell off before and probly still not remove enough ...

I disagree with #26

Lime green is Okay if and only if it is a new Lamborgini.

Gotta keep my options open.

Just thinking if it is hung, yank a valve cover off and give it a look. May get away with tapping valve back down. A bad spring or a bent push rod could be the culprit as well.

All can be taken care of fairly easily in the water with little out of pocket expence.

O compression can be a hung up valve.

If you running on the old glass tank with ethanol it sounds like a very familiar problem.

What engines do you have?

Did not realize you are a stones thru away from me.

I have a shop too, its beginning to look like a Machine Shop forum here.

We tell our guys to hold shafts supporting them in aprox. thirds. Simple and easy to figure out how to hold

A few cents to throw into the pot. Keeping it real simple as you have a big problem and that makes finding it easy. Packing- If traditional flax it should leaking a bit, if it's not it is too tight on the stuffing box. A drip every minute or so is fine. Too tight and it will make shaft hot, not wobb...

If you have to change the 31B that much, do you really want a 31?

$1500.00 in 3/16" SS? Something does not sound correct unless he is a TRUE BUDDY of yours as that will only cover the cost of Materials. SS may be a great choice if done correctly, get a few more prices then do some comparing ( Materail Grade, Filler Grade, Welding Process, Welder Certification or r...

Been there, done that, sorry to hear.

Hopefully some shafts, wheels and you will be back to fishing.

To clean out a coupling I prefer to use a Flap Wheel, such as a McMaster Carr PN # 473 4A 767. Using a Flap Wheel I prefer the wheel is slightly snug in the hole so it centers itself. The Flap Wheel goes into a drill or drill press, spin it up, insert into bore and move wheel in and out of the bore ...

Seems like a run of the mill article, factual but not overly interesting to those not afflicted by the problem. Leaving out the possible safety issues that may arise leaves me at a loss, it is a major concern. As said, most people may glance at the article, those not in our Vintage Boating Community...

My .02. I lost a bundle of money and time because of the Ethanol mix. If I can rattle a few branchs or make some waves, sure I am in for it. However I do not expect anything to really come from it, we are only a few people yelling while the majority of people don't really give a dam. The short story...

Good thing it is a center console boat.

Imagine what kind of problems would have become noticable if it had an enclosed helm.

It is quite possible when I got some E-Fuel on my empty tank several years back and developed immediate problems it was bad gas (Phase Seperated). The marina had just changed hands and new tanks where put in. All fuel was E-Fuel and the Marina did and does have a problem with water in the tank. I al...

I ran and had problems soon as I put 30-40 gallons into a fairly emtpy tank. I had been running for several years with it (ethanol blend) in small doses to top off the tank at the end of the year, maybe a bit rough starting and idle was off a bit, but it ran. We used it up here as a Winter Blend so ...

Rob Tomsho and I played a bit of phone tag while I was on vacation. We did finally get around to talking and as mentioned he was well informed on the problem. He mentioned he would send an e-mail with a copy of the article when it came out. I would be leary to have Marina's sell Avgas, sounds like a...

It don't take much to make the 440's run warm. From my 12 years with the engines I have found: -Old raw water impellors will not pump enough water. -Worn cam in the raw water pump will not pump enough water. -Clogged anything will not pump enough water. *Check for debris in oil and tranny coolers. *...

What the hell was he thinking...everybody knows it's the shaft that swells in the water.

Not sure if this is feasible for you, but could you add a fuel compartment to the new tank for long trips. Basicaly just a baffle without holes. It could be closed off and cleaned out when not being used. Make your main tank compartment very similier to where the old once is/was so trim stays the sa...

I was under the impression White could be water or antifreeze. Maybe from engine or perhaps not enough water running thru the dumps and making steam. If "detergent blending" is the issue why are we not seeing this problem in our cars to the same degree as our boats. I do have to say ethanol did caus...

I can say changing the tank from Glass to Alum has me running again. Whether the tank will last 5-10 or 20 years, don't know, don't care. Just about every other boat runs alum tanks and so will I for several years, till either it rots out or something better comes along. If I go to sell boat, my sel...

Peter, Glad to help in any way. My boat was used to pretty much everything til the goo set in. Lots of Fluking with the family, trawling for Bass, short 1-5 mile runs. Weekends trips to the inshore grounds for Shark and Lil tuna's- 20-30mile runs. Also the Beach runs are 10 miles each way and the sa...

The goo builds up, then hangs up valve train, glues carbs shut, fouls your plugs. Then keep in mind the goo is coming from the tank itself, you can only take so much resin from the fiberglass before fails. Not sure where you are running to and from, but I was plagued with problem and it is not fun t...

It's the people and not the places that make everything worthwild in life.

New place, good ole people, hopefully minus one.
