70 mph "cruise" speed with 28's? What rpm is that?

article said 4000 rpm

I have been told that the prop was labbed.

Article was written on the Maui Jim 1998 33 pp

Thats cool thanks. 4,000 rpm sounds high for a cruise speed to me. Mine is not doing 70mph at 4,000 with labbed 28's

what year boat do have and power?

what speeds are you seeing?

I am in the process of repowering now

If you choose to go with blowers, I am selling a Littlefield 8-71 with matching carbs, fuel lines, regulator, linkage, belt, pulleys, and a Whipple intercooler that I just took off my pp.

37 hours percfect condition

If you use the mercury racing website's slip calculator, that is 1% slip. Sounds pretty optimistic to me. http://www.mercuryracing.com/propell...calculator.php

I have a 2000 with HP500s, labbed 28's. My cruise at about 3500 - 3800 rpm's is like 53 to 55 mph.

The best slip # i have seen are truly on a PP33 ,,,mine where 6 % some people say u can't get below 10 but ,,oh well.:party-smiley-004:

But 1% is very very optimistic !!!:grinser010:

Recommendations for a block want to stay with a short deck so I don't change the exhaust . what crank & rods & pistons should I use also whats the best compression for marine engine would like to burn reg unleaded I'm think 10:1 like I said before this is new for me street cars are a different animal

I'm confused...

If you go with a tall deck, you won't have to change the exhaust.

For example, most all aftermarket heads make HP by raising the exhaust port up to 1 inch (mine are just that) and the exhaust conforms to the change via. the rubber boots.

Am I missing something?

Ok like I said this is new for me didn't know if there is any clearance issue thats why I'm here asking questions . Only want to do it once. Looking for help from the guys that been there done that
