[QUOTE="Ranchero50, post: 221020, member: 1523"] I don't understand your question. Replacing one 70hp with another isn't going to make much difference, especially if the new one is low on power. If you are out of shim then I would replace the liner, it was only $60 with a new impeller key and sleeve for a 90/65, cheap enough to be a maintenance job. I'd replace the liner, then see where the engine is revving wide open and go from there. I would not swap one 70 for another, doesn't seem like you'll gain anything (on paper). Jamie [/QUOTE]
