I have a 1992 Sunbird center console in decent shape and my 1991 150 HP Johnson just bit the farm. My boat documentation says that my transom can support up to a 175 HP engine. I have 3 options (as far as I know). <br />1. Rebuild the engine. I was quoted a price of close to $5k. To spend that money on an engine that books for half that value does not seem to make too much sense.<br />2. Buy a new engine. I have seen decent deals for year old plus new engines. Average price seems to be around $8k, plus install. <br />3. Buy a rebuilt engine. I was quoted prices of $3,500 for a Johnson 1991 150 hp, $4,100 for a 1994 Johnson 175 Ocean Runner and $4,500 for a 1997 Johnson 175 Ocean Runner. Also, he will give me $400 for my old engine. All 3 engines have carb's. The guy who rebuilds & sells these engines uses new OMC power heads and offers a 90 day warrantee. He has given me several customer references. The one interesting thing that he told me is that he will not warrantee the variable rate oil injection setup. He feels that they can be faulty & be blamed for most blown Johnson engines. He wants you to manually mix the oil with the gas. Mostly becuase of the year and size I have been leaning towards the 1997 engine. When I told this to the guy he said fine, but it is his opinion that a 1991 OMC product is built stronger than the 1997 OMC product.<br /><br />Right now I am leaning towards option number 3. What do you gearheads out there think? How many hours should I be able to expect out of a rebuilt engine? I would greatly appreciate any opinions out there.<br /><br />Thanks
