I have a friend with a 130hp Honda mounted to the stern of his 540C Northbank. By all accounts its a great motor albeit with a hefty weight penalty. He had no end of problems with his set up in regard to hole shot and in the end against my advice (gained from posts here and in other forums) he opted to fit a fin to the motor which has alleviated the problem and he reports much better response from the beast now.
In discussing my own experiences with re-propping my TLDI and the effect of pitch on ones rpm, we got to discussing his max rpm and to my surprise he told me he is only getting 4500rpm @ WOT. I was shocked, because I did not believe that this fiqure could be right and definately not within the manufacturers specifiactions. He's happy with it because he is getting around 40mph at full tilt, but I have read here before that over propping (I'm assuming this is what he is experiencing) is detrimental to the overall health of your outboard. Is this right?
I am trying to get the pitch of the prop from him for your (AUSFISH members) advice on the subject so hope to have that soon. Obviously, the 130 is no longer available and the only specs I could find were for the 135 which has a max rpm of 5000 - 6000rpm, well over what my friend is achieving.
