There is no thermostat on that motor, right? On those motors, make sure not to overprop them, as the cooling is mostly based on the engine RPM vs load. Speed of acceleration should not be an important factor, as I would not think it affects overall cooling. So, rebuild the waterpump every 3...

My neighbor's 24 footer had the port pontoon damaged in a storm. The front of the pontoon was torn open. The opening is say 12" long and 1/2" wide. Can this be welded shut, maybe by welding on a piece of aluminum angle iron?

My neighbor has a really ugly, rare BMW? (maybe Mercedes) stolen. It looked like a half SUV/car with a big roof rack. Really ugly in a nerd kind of way. Most cars are stolen for parts, hence corolla. This theft was baffling.

Gee, for a long while the Corollas were the most stolen.

Check your spark plug wires. At the age of your motor, the insulation can break down. The conductor is stranded stainless steel. The boots and springs can be replaced for cheap. If the springs are rusty, it makes sense to replace them. Are the coil ends push in? If so, you could make up a...

Gee, I hear from multiple sources that Stellantis is going out of business. I have always thought that they messed up the Jeep brand, and their other brands are pretty much out of touch with consumers. The shocker is that Nissan is predicted to go out of business as well. Nissan sold a lot...

We had Hurricane Sandy in 2012. It drowned all the bunnies and mice, which has been good for us. The bunnies have been relentless eating all my plants for the last 4 years. The mice have invaded my garage. Traps of all kinds were ineffective. The weekends NorEaster flooded some stuff...

As far as I know, metalflake is paint, not gelcoat. I would like to be corrected by those who know more. The top finishes on the top yachts are alwgrip or Imron which are two-part polyurethane paints.

I would expect Porter-Cable to have a rebuild kit for that nailer. I bought a rebuild kit for my Senco FR framing nailer at Amazon.

The OP stated that he can get 4800 with a 19P prop, and above that RPM he ventilates. Redline is 4600, right? I think he should try a 21P prop.

OEM Reed valves do not usually go bad. They may be slightly open at rest, but close well enough to seal. If the motor doesn't idle, the reeds could (could) be to blame. I did not think reed stops were adjustable. They are factory bent to allow the correct opening.

The bendix engages the ring gear when the starter starts to spin. Once the bendix gear is kicked out, the starter and gear must come to a complete stop, in order to engage the bendix gear again, when the starter starts to spin. The rule of thumb for Starters is about 300RPM cranking speed of...

Buying the wrong pitch or style of stainless prop is an expensive mistake. I would dial in the pitch and style of the prop with an aluminum prop. When you have it, then go to stainless.

That is not usually a starter issue. The bendix is designed to kick out when the engine fires. The engine is not supposed to fire only once, however.

The Bendix will kick out and not re-engage, when the motor fires. It is a common problem on all engines and can be solved by tune up or altering your starting procedure. So, pump the primer up until hard. Hold the choke button and crank the motor until it starts. Is the Quick Start system...

The PTT system needs to pivot a bit on the upper and lower pins. Maybe it is binding on them?

Gee, if grease doesn't fix it, the second choice would be the PTT motor slipping while driving the pump. I do not know if that is possible on your motor, however. Mercury PTTs often have an adaptor from motor to pump. They could strip out.

Try the Turning Point in 21P. They are pretty high performance and hold the water pretty good. They are also cheap enough. Different year Alpha Drives had different gear ratios. So, if you get a recommendation on a particular pitch prop, it makes sense to find out what gear ratio you have vs...

I think you need a PTT unit from the 3 cylinder Mercs starting in the early 70s. I think you can also use one from the 4 cylinder 50HP Merc of the same vintage. I do not think the PTT unit from the 4cyl 800 or 850 or any IL6 will fit. The PTT system consists of 2 PTT brackets, PTT...

You might suspect the top main bearing of knocking. I do not know if you can check it by pulling the spark plugs and moving the flywheel checking for play, but you might try it.
