I can get a good deal on a 150 h.p. 1995 ocean-pro Evinrude for my 21' Outrage. It is a 25" model and the reference page as well as my measurement from the top of transom to the bottom of hull is saying 20". The seller is telling me I can mount the engine high. What you obviously can't do is the opposite, mount a 20" on a 25" hull.
My question....
Is it acceptable to mount a 25" motor on a 20" transom?
I'm aware there has been a recent thread about a 13' Whaler. I'm asking specifically to avoid consumer's remorse.
Thank you in advance for any replies.

You will need one of the many varieties of Jack plates in order to raise the engine the needed 5". They come in both static (fixed once bolted on) and adjustable, both manual with a large center lifting screw, and hydraulic operated, like power trim.

Don M here has done your exact installation.

Thank you for the answer.
Is there a way to find the posts involving this particular installation with Don M.? I'm new to this board and appreciate any help I get. AkWhaler

If you can wait a day or two, there will be a new article with detailed photographs of raised engine mounting.

You're right! Don surfaced on my original topic (21' whaler hull #00405) over in the general forum.

http://continuouswave.com/whaler/cetacea/cetaceaPage56.html shows in detail the mounting of a 20-inch shaft outboard engine on a 15-inch high Whaler transom. This same technique may be applicable to mounting a 25-inch shaft engine on a 20-inch transom.

Great article on Jack Plates. Once again I am in awe at this web site. For anyone following this thread I've decided to go with the 115 Merc. Someone else beat me to the 25" 150 Ocean Pro. Snooze you lose, but I still feel a little P.O.'d about it. I was taught and put in practice when you have a deal going you stick with it. Well I'm off to learn about getting a 115 Merc back in business after a 10 year slumber. Thank you for the input.
