Re: chevy outboard difference

I think GM only used the 230 in 63-64-65.In 66 it got replaced with 250.

he had an 81 thompson sidewinderx-19 sold it for 400.00 cuz the motor locked up showed me pictures and the valve covers had 230 omc on them thats why I assumed thats what it was. Wish I could have got that deal.

I think he means the 230 Hp motor not the 230 CID motor. and I think the 230 CID was inproduction with the 250 CID and there were at least 2 versions of the 250 CID. in cars it was common to designate by CID and boats did it by HP. just marketing

Nope!!!The 250cid replaced the 230cid.in 66. They wasnt in production togather.They did have two or maybe even more versions of the 250cid.I believe GMC even had a version of their own.If they were in the same year,I dont know about it.If they did,I would like to know more about it.When he said 230,I thought he meant CID,that blowed my little mind!!
