Re: Notching bow ply

Search on "transition joint". You will find your thread where I posted the pictures about half way down. I don't have access to my pictures right now. It's called bow notching on a malahini. There are many examples just searching on transition joint, though.

Re: Fuel tank vent

It takes less than 0.5 psi to lift or push fuel 12" straight up. The 5/8" fuel line will be less than a square inch. Your fuel pump will handle it. I haven't had a problem with that.

Re: Fuel tank vent

I ran a hose from the tank vent nipple to a fuel vent fixture in the side just below the shear. I put a loop in the hose to keep water from sloshing in. Nothing complicated.

Re: Key Largo Build in Charleston

You have a good point, Matt. On my engine, raw water flow is not thermostatically controlled, so all the water the raw water pump is producing is going out the exhaust as fast as it can pump it. Temperature is controlled in the fresh water internal system. There is way more to this than I can compre...

Re: Key Largo Build in Charleston

Originally I was at the impression 3" dual would be sufficient. I was aghast at the thought of dual 4" exhaust pipes in the Torpedo but I stuck to the manufacturer's minimums to avoid any warranty issues on a very large investment and avoid future problems. Their knowledge and engineering expertise ...

Re: Key Largo Build in Charleston

Crusader recommends a minimum 4" for single exhaust and 3" for dual exhaust on 5.0 L V8s. 4" minimum on all engines larger. This goes back to at least 2014. Perhaps the increase in HP over the years prompted a revision in their standards. In any case, I yield to the manufacturer recommended standard...

Re: Key Largo Build in Charleston

Reducing the exhaust diameter from 4" to 3" reduces the area of the piping by over 40%. Not a good idea.

Re: Otter's Ski Bass

One of the things to consider is the size of the helm pump. The smaller the number the more turns are required to go from lock to lock. Most lower priced systems usually include a 1.5 pump. These will generally need 4+ turns. I run a 2.4. It requires about 3 turns. Go to Seastar for information and ...

Re: Otter's Ski Bass

If you don't mind the extra expense, hydraulic is very nice and very precise. I think the Baystar is part of the Seastar line. You may find more information on their website.
