Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Jack plate or transom build up?

I'm a new member who has loved Whalers since the 60's on Barnegat Bay.
I recently took possesion of a 69' 16 foot Nauset(?). I would like to repower it with 70-90 hp 2 stroke.
I was told by a Whaler dealer the only way to put a new engine (20" shaft) on it is to build up the transom. He said no to a jack plate. My mechanic who works on my other boat says a jack plate would be fine. I'm a little confused here and would like any advice on this. It has a 86' 50 Force on it now and I'd like more power and reliability that a new engine will provide.

Tom,

You have received a lot of misinformation....

Your 16' hull takes a 20 inch shaft motor...
Just bolt a 20 inch shaft motor directly on the transom and you are good to go....

The only boats that may need a jack plate to raise the engine up 5 inches is the early 13 foot models. These models used a 15 inch short shaft engine. If people want to add a 20 inch long shaft engine on these 13' models, then then either need to build up the transom or add a jack plate.

Every 16 foot and 17 foot model use a 20 inch long shaft motor directly mounted on the transom.
That is if no one has cut down the transom...
