help 60 70 75 hp johnson evinrude guys for phill
Hi Phill,
Now you will get lots of good input from lots of people I am sure!
remember also with props that if its stamped 24 it may be actually 22,23,24,25 or 26 by some one elses pitch mesure. measuring pitch is very hard. I have bought a 19 pitch in the past that was actually more like a 24 when tested on boat taking the speed revs and gear ratio calcs. I think some of the 75hp stinger motors had a 1.86 to 1 gear ratio but I may be wrong.
When you get that boat of yours set up and wound out you better hold on!!!
I aggree with you in that the motor should be no set back on that hull, It will make it safer and your hull looks like it may want to porpous if set up wrong, My feeling is surface pierce but not to much.
I would get the nose cone on, just use two part filler- forget the low pick ups. and if you can get your hands on some cleaver or chopper props to try in the 22 to 26 pitch range would be a good start. Remember you can always move the props that dont work on your hull out via ebay as I do (trial and error).
Any 60 70 or 75 hp guys please add your info for Phill

I Have Wanted To Make A Gearcase

My dad made my brother a gearcase for his "A" Hydro in 1949 and my brother beat 32 "A" Hydros in the Hearst Regatta.
Because gearcases are in my DNA, I have wanted to make a stainless steel gearcase and part of that concept was to have the water pickup in the skeg.
A stainless steel gearcase could be made very thin and the skeg could be larger but thinner...
Maybe, in my next life Tim.
