Just bought a bullet 20 with this engine. I'm trying to get all the information I can on this engine. Is it considered a good engine? bad engine? Things to look out for? Thanks.<br /><br />Bob

Great motor! It likes Champion plugs, 87 octane, good oil and rpm. It doesnt like being lugged. Thats a good boat that responds well to rpm. Target 6000 rpm with an average load.<br /><br />If its new to you and you dont have a positive history, change the water pump. You may consider cleaning the carbs if its been sitting or you dont know for sure.<br /><br />Good luck and welcome!

Also might change the gear oil & tstats.

Thanks for the feedback! I'll go through things on the engine before using it. I've got a manual ordered but in the meantime, does anyone know what the compression should be? (wet or dry) Best oil to use? Is it a good idea to also put a little oil in the fuel?<br /><br />Thanks<br />Bob

As long as the compression is no more than 15 lbs between high and low its good. On those motors one bank may be about 5 lbs different than the other.<br /><br />A bit of oil in the gas cant hurt especially while you are verifying the oil pump works.<br /><br />Good luck!
