I have just purchased a 1964 Nauset with a 1979 Johnson 100 HP. I would like to repower and have found some good deals on the following Yamaha 4 strokes.
A F100 2003 @ 356 lbs. and a F60 2002 @ 244lbs.
The 1979 Johnson 100 weighs 300 lbs. and will pull 3 skiers. I don't plan the need to do this.
My questions are:
Is anyone running either motor on the same kind of boat?
Is the F100HP too much weight?
Is the F60 enough power?
I have looked into the Suzuki DF70 and can buy the F100 about the same price. The F60 is about $1200 cheaper. I also like carbs because most guys can work on them, who can fixed DF (no local dealer)???
Thanks, Jay

I think you will be happy with the 60. I have the DF70 and am tickled pink but my montauk weighs more than yours. The 60 should give about the same performance as my 70 does on the Montauk(28 cruise@4k..39WOT @ 5.5k).

This subject is covered ad naseum in the forum under various threads, so with a little bit of digging I am sure that you will have lots to think about. My own decision process in repowering my 69 Nauset was that the F100 @ 356 was more weight then I wanted on the back of my boat - I was worried about static trim as well as handling. The 4S are also larger engines physically it seems in terms of dominating your transom. I went with a Yamaha 90 in the end.

Ron, I just found a used Yamaha 2000 90 2 stroke. It's the same engine that was on my 2000 Montauk. It ran great with little to no smoke. It's about half the cost of the F60 so I'll pobably get it. Regards, Jay

Nick, you know the routine. If the price is right you win, if your close enough you win both:)Regards, Jay
