Hey everybody, I bought my first boat a few months ago ('89 LIberator 241) after spending last summer on an '88 211. The previous owner repowered my 241 with a 7.4 MPI so i thought this boat might scoot. Well I was wrong. The 211 would do 55 GPS'd anyday with 2 ppl. I can only get my 241 up to 38 GPS'd with two ppl and full tank of gas. The prop is a Merc Marine Offshore Series 48-825902A 46 21P 4 blade aluminum. 1.50 ratio. My max RPM has been 4700. Doing the math I've got about 39% prop slip. The boat does have bottom paint which I thought might add some drag. Any suggestions on how to make this boat faster or is this what I get for having such a big heavy boat and a stock big block?
Thanks for any input.
