I know it destroys steel when in contact (look at old tractor rims that have been loaded). Brass gets a light green haze on the surface, but I can't recall seeing the affects on aluminum. I would think it would be similar to salt. Might only affect it with contact.

Most manifolds will allow you to remove the valve covers but you will need a 1/4" drive ratchet, 6" extension, and either a short 7/16 socket with a universal or a 7/16 wobble socket. Do try and tighten them first, but if they are cork they will leak again. Felpro makes a marine specific g...

If you want to see something scary, look inside an ethanol storage tank after being in service for a number of years. It reminds me of the inside of a 80 year old boiler. Lots of rust and deterioration.

All the gas stations within 50ish miles (maybe more) of me are served from 3 different terminals. These terminals recieve the product from a pipeline running through West Michigan. All base products (gas, diesel, kero, etc) are pumped through the same pipe. The line either gets purged or they run a ...

I have to agree with Jeff. From my years working on boats and equipment the ethanol only hurts when the gas doesn't get used. I have always run pump gas in my boat with no problems. I treat it with marine stabil at the end of the season and it starts right up in the spring. I use up my gas every yea...

I have to agree with carl. Cupping the props will only reduce slippage, not drastically change rpm. I also think that you should be running faster than 4900rpm with the props you have on there. I wonder if your valves are starting to float (chryslers have very weak valve springs in their industrial ...

I just stumbled across this and loved it! It has a small amount of language that may be offensive to some, and an interesting way of delivery, but I think this guy did his research. https://youtu.be/wpH3SEczlNo I had to laugh about the train comment because I have been building a 2.5" scale ste...

I think somebody made a suggestion based on 1:1 gears and I am gessing you have reduction gears. Way too small of a prop. If you go down in diameter then you must increase pitch. 16x15 is the factory size for a 32 with twin 318s and 1.52:1 ratio. 14x10 for 1:1 3 blade for both. 14" is the small...

Check the top of the trans cooler. All the rust particles from the exhaust manifolds tend to collect there.

The sea water intake hose should go to the bottom of the rear pocket. The top of the rear pocket discharges into a tee that feeds into the front of each exhaust manifold. The fittings on the bottom of the aft end of the exhaust manifolds discharge to a tee, through the trans cooler, and through a 1&...
