One of my friends bought a brand new 46 HP sometime in the mid 80's and I remember talking about the
differences with the hull. Along with the keel redesign, the hull was also strengthened to compensate
for the additional power. We were out playing with his new boat and did well over 30K averaged on
several reciprocal runs. This was in Panama City Beach, Fla in the fall or winter as I remember it was
cool at the time. That was quite fast for that time. Today the demand seems to be for 40k or more.

Re: 46 Convertible refit begins
Dig through the forum posts and I'm sure the information is there on HP. Dave will probably know as well. I recall hearing something about slightly larger shafts? And maybe a little bit more beef in the stringers?

Re: 46 Convertible refit begins
Thanks everyone for there input. Seems like there is a few different opinions in regards to this. I will keep digging for info but at the end of the day I’m tending toward the suggestion of just pulling back the sticks. Mick

Re: 46 Convertible refit begins
So...Mick, if you get a second, could you let us know the rationale for going with the 92 series engines rather than just rebuilding the 871s you've already got? Seems like a lot of extra work and $$$ for not a lot of additional BANG, if you know what I mean.
Cheers,
Q

Re: 46 Convertible refit begins
Just to put some context around our plans our estimate is that we have to rebuild either the 71 s or the 92 s. We have got. Guy that will do this for about 7k each and I suppose by time we do the turbos and all the other auxiliary items then they will prob be about 10 k AU each. We are purchasing the second hand engines that are currently in a 50 ft boat and have only done 1600 hrs. We still intend to rebuild these as well. These engines are 1998 model 625 hp and electronic controlled and for 25 k au we get everything from the controls to the props. Our 871 are only 430 hp est so there is a significant increase in Hp . We removed the engines today and I will post some photos and I will try and post a video if that’s possible. Based on the info what everyone’s thoughts on the rational ? Regards Mick

Re: 46 Convertible refit begins
So today we removed the engines and generator and was able to pressure wash the engine room. I tried to post a video but with no success ? Is it possible to post vids on this forum? I will post some photos. Regards Michael
