your boat model
 

Hello your boat model is 1988 :hi:

Yes tsubaki i am sorry coz i see pic here

Naah, it's '77 or older, like FERM was sayin'. Look at the floor hatches.

Definitely a 70 to 77 vintage. You know though, with the V20's, newer is not necessarily better. They are all great boats, and the older models have a lot more teak than the newer models. The only teak I have on my 1991 V20 cuddy are the hatch rails. Lexan door to cuddy, roto-molded rod holders, etc.

I just took a better look at the pix you posted, and, please do feel daunted, but you have some work to do on her. If, however, you are mechanically inclined, have decent tools, and patience, you can have a real gem of a boat. All the technical advice you need is here for the taking thanks to the kind, smart, experienced and generous folks on this site. Go for it.

As far as re-powering your V, 150 h.p. seems to be the ideal combination of weight, speed and fuel consumption. There are lots of threads regarding horsepower, and we have folks here running outboards from 90 h.p. (with surprisingly good results) to 225 plus. 150, however, seems to be the "sweet spot" for the V20.

Good luck with your project
