Rebuilt Mercruiser 140/3.0 doesn’t have enough power to plane

Yeah, there’s a good one pretty close to me which did the original work. But that MichiganMotorz engine isn’t too bad. If I rebuild the current one, the mechanic would be the one to do it. So it may be a wash in terms of cost since his labor is pretty expensive. The block may have to be rebored if the scratch is deep enough. I’m not sure how much farther they can go as it was already bored .030” over. I assume I’d have to get new pistons too.

Are there other costs to a rebuilt motor I’m not considering? Like the freight costs?

I got a new base engine from Mich Motorz 6 years ago, it was $200 shipping to my work, maybe 150 more to a residence with out a loading dock.

I spent about another $500-600 on gaskets, gimbal bearing water pump. You may want to look at your rear engine mounts in the flywheel cover and change while they are out. Check your manifold for corrosion leaks and cracks no sense wipinganother engine on a rotted manifold.

I was debating are build vs the new, at that time was less than $1k diff between the two. After 6 trouble free years I'm very happy with the project.

Wow, If the floor was soft and layerd over, then got soft again, I'd say the boat is on it's last legs. The stringers and transom are next to fail.

and lots of work to get it safe!
