Go by the book. 35lbs sounds right. I have never seen an oil pump come loose, ever.

Distributor/oil pump drive shaft and gear is a separate part from the distributor that fits down in engine block. Distributors are identical and interchangeable. The drive gears are machined with opposite helix to give reverse rotation to crank and cam while retaining clockwise distributor rotation.

Last Question - Looks like the hole coming into the boat for the shaft, don't know the technical term for it, is about 1 1/2 inches I.D. That does not leave a lot of room for a 1 1/4 shaft. Any issues running a larger shaft through there? Want to go from 1 to 1 1/4 to run a larger prop. The rule of...

My jig is set up for 1.500" od bearing.

I had to make my own. I do have the jig that I used. If you have the ability, or know a good welding shop, you are welcome to use it. Just cover shipping to and from. You will have to check a few dimensions to be sure it is the same. I have a good welding shop in Michigan I use that could probably m...

Let me know if you need the parts. I should have a few sets.

This water blasting is becoming very popular, and for good reasons. The first time I saw this was a contractor out of Ohio blasting and painting locomotives for G&W railroads around Michigan. Last fall I was working on a lift at a marina in west michigan. A contractor was water blasting the bott...

I will second the advice on the standard pump. The high volume will only bypass the filter when cold and cause oil leaks when warm.

Just make sure you clean out the pickup tube and suction screen well. Many a new engine has met an early death from dirty suction screen.

When I build engines for boats, I always set them up so the dipsticks and oil fill is easy to get to. On most twin engine boats that means the inside valve cover gets the oil cap. Makes life so much easier.

Depends on your engine and wether or not it is stock or cranked up. Chryslers used a pcv in one valve cover and either a breather or vent hose to the spark arrestor on the other. Doesn't matter which valve cover is used for what. Mercruiser, Crusader, OMC, PCM and others only used a vent tube from t...
