I recently purchased a 2000 Zodiac YL275R RIB and put a 1989 8hp Johnson (15" shaft) on her.This was the max recommended hp.With just me (215lbs) and the 5 gal gas can it took about 6 to 8 seconds to plane then it went like the wind and was quite sensitive to tiller movement.When my wife got in 120lbs (forward and opposite to myself) we couldn't get it to plane at all.A couple of questions with just myself in would trim tabs or a foil on the outboard help plane quicker? And is it just a lack of overall hp to not plane at all with the 2 of us in it? And would going over the recommended HP to maybe a 9.9 be a problem or solve the problem?
Thanks.
