To me anyhow. Been browsing the forums for weeks. Only have a few dozen questions. Picked up this rig on a Aquarius invader. Been sitting for 8yrs and motor fired after 5 cranks. Motors been stored tilted up all this time. When I lowered it later I noticed oil leak out of prop a small pool. Drained lower unit and oil was dark black. Drained and refilled seems to have ever slightest leak. I barely feel lubrication on finger when running it along bottom of skeg but no noticeable drops at all. Could it have leaked upward being tilted all the way up then when lowered came out prop?? Purchased gear housing seal kit and seloc book. Book doesnt go step by step like I hoped. Also while running on muffs no noticeable water coming out exhaust holes. I read that 77yr models don't have much noticeable water spray and can get #1 cylinder hot. Seen conversion for tap in upper block for water to spray thru cowling. I'm a little apprehensive to drill thru block. Are the t-stats located under heads on bottom near cowling? Spent half a day freeing seized steering cable. Also purchased new impeller. Getting ready to tackle this monster. Any suggestions for this backyard wannabe mechanic? Sure like this old rig and can't wait to get it on the water.
