Howard Sterndrive, I just finished repairing the hull, floor, front and rear motor mounts, and transom on my 1977 Seaswirl with a 140hp OMC. I could not believe how everything was built originally.... It IS much better now. I took photos and measurements for everything before I started and am now ready to re-install my motor. Originally there were two plywood shims under the rear motor mounts. One about 3/8" and one about 1/4" and I don't know which side was which. Having spoken to a local boat repair shop, he advised me that there is a correct measurement to have the motor set into the boat. I did not know about this and even couldn't have gotten it before I started the rebuild as the motor mount area was crushed from rot and the weight of the motor. I have seen the diagram you have posted for a V-6, do you also have the specs for the 140hp 4 cyl ? Any info you may be able to share is greatly appreciated !
Thank you,
John

jkgaddis I moved your post into it's own topic: When you get a chance, please review our forum rules. We ask that you don't post to topics over 90 days old unless you're the original poster.

Your own topic will help get things moving anyway.

When I get a chance I'll look through my stuff and see if I have any detail on that mounting.

No worries.

I'm afraid I don't have a diagram on the mounting for that set. I'd be stuck Googling same as you.
