I will have to check the trans for the ratio this weekend. But I pretty sure it is a 1.15 to 1.25.

There are no cabin under the deck. I have v berth, dinette, and stacked bunch beds.

I think my max rpm is 4400. Trying to remember from last year or more like 2019...Maybe 23 mph. Yes I have 3 blade 16 x16 cupped. With half to quarter tank of fuel.

Yes it is an express and gear ratio I would have to check, but whatever a 454 330hp crusader had.

I have a 1982 10M Express, what is the best prop for the boat. Mark IV 454’s with 16x16 cupped is what I am currently running. The best cruising speed I have seen is about 17 mph at 3300. I called Henry Smith Propeller a couple years ago and the suggested 15x15. I thought 16x16 cupped was close enou...

I also used the good motor and pump to back flush the other motor and pulled four impeller blades out of that motor. So now I can confiden...

Just in case it change during the last little bit, imppellar was good. than ran motor with the hose discounted ...

Well didn’t do the water pump yet. Pulled hoses off after trans cooler and before heat exchanger and checked flow between the motors at idle. Gave the motors some rpm and the flow is solid out of hose Of good motor and no change on the bad motor. So I think it might be a bad hose from the thru hull ...

I have a 1982 10m, with 454 350hp closed cooling that is overheating and melting exhaust hoses. I am at a loss as I have done just about everything except replace manifolds and circulating pump. The impeller was new and checked good flow. There is no coolant/ water leak outside the motor and no choc...
