I have a 2000 90hp Johnson with a bad cylinder (broken sleeve). This was not an oil related failure. I have been told it can be re-sleeved. I found someone local who has been in business for over 20 years that will resleeve it for $250 plus $9 per hole to hone. I have rebuilt motors before, but they were all 4-stroke car and motorcycle engines. I am very mechanically inclined. <br />I have a couple of options.<br /> <br />1.) I can tear it down and have it resleeved/honed and rebuild it. No warranty on failure here.<br /> a.) replace only those parts that failed for about $500.<br /> b.) replace all pistons, rings, bearings, etc. for $1000-1200.<br /><br />2.) I can get a remanufactured powerhead for around $2500 (2150 after core) or maybe a bit less with a 12-15month warranty and install it myself.<br /><br />Also, I have been looking at the Johnson parts breakdowns and it appears the differences between 90 and 115 are all in the powerhead. I could eat the core charge (or maybe not) and up it to a 115. My boat is rated for 120 and runs about 34mph now.<br /><br />What would you guys do?<br /><br />Edit 1: Where would you go for parts or a powerhead? I've seen them listed, but who has good products/reputation?<br /><br />Edit 2: I have found a new 115 powerhead for $2740.
