Thanks everybody for the helpul hints! i did decarb it this afternoon, although it was before Willy's post so i couldn't try what he said. I used Valvetech Engine De-Carb. We plan to take the boat out in the morning for a test run. I'm beginning to think that the 15 1/2" prop on the motor is too big cause of how much gas we burn. When i was reading a Boat US catalog i discovered that the motor should have a 14 1/2" prop on it, and luckily the 14 1/2" prop on my Yamaha fit it! So we plan to test the fuel economy on it each prop and see what works best. And i also do think the mechanic told me a bunch of BS. I'll know when i drain the lower unit fluid in the morning and after we take it out. If that doesn't work i might just end up putting a Yamaha 150 25" shaft on a jack plate on it! ;D But for right now the motor is running dam good :D
