Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: F90 Engine for 1979 Montauk

Hi All. I just picked up 2004 Yamaha F90 for my classic 1979 Montauk.

I still have to purchase the controls and gages. The F90 is a four stroke motor, FI with a 25" shaft, power tilt & trim.

I will mainly use the boat for cruising the bay with two to six people, maybe a day of fishing near the coast.

Question:

What problems should I expect with the 25" shaft since a 20 " shaft is what's called for? The motor weight in at 379 lbs without the prop. Any special precautions I should take when mounting the motor? What prop should I get? Any suggestion on prop, controls,or gages?

I'll appreciate any suggestion or recommendations. Thanks.
