I have an old 91 Fs Surpass. No Roman numerals after it. What does it compare to in power to todays four strokes? Is it about the same as a Saito 82 or a YS 63s in horsepower? It seems fairly heavy compared to my Saito 100. It is getting the crockpot/antifreeze treatment right now and I thought I might fire it up with a 15-4w prop tomorrow and see what it will turn.

It should be fine in a 4 star 60? I think they used from a 13-8 to a 14-6 back in the old days?

Enjoy,
