I have a 2007 bravo three with just about 980 hours. It’s the 2.2:1 gearset, I believe. I assume it is still the original cone clutch since I’ve owned the boat since 500 hours and I have not changed it.
Saturday I found something on the bottom even though I was in a channel. I was maybe running 1800 RPMs plowing a little bit. Sounded like I hit something metal that was in a mound of sand. After the initial clunk I pulled the throttle back, and the sand stalled it. Wasn’t a very hard hit and didn’t think too awful much of it as I was on my way home anyway. Definitely not enough visibility to check it visually in the Caloosahatchee. Tilted it up, fired it up and ran the rest of the way home. I didn’t notice anything out of sorts as far as vibration or performance issues.
well…
When I got home, I threw my goggles on and hopped in the canal to check, and this is what I found. Also found a little bit of fishing line wrapped around the small shaft seal, and that seemed fresh.
I went ahead and threw my four blade 18 pitch wheels on (The ones on the boat are three blade 20s)
other than the lackluster performance of the uncupped 18s, everything seems fine. Time to get on plane is obviously improved with a little loss up top. No vibrations and it doesn’t seem to be losing any fluid from what I can tell.
But now here’s my issue!
I usually run my lube bottle right at the lower level line. Every time I open the hatch to check the oil before I go the level is right there. I have never noticed the bottle being completely full to the top during operation. I don’t usually make it a point to check my lube bottle while we’re cruising, but I seem to remember about 3/4 of an inch of rise being normal
Obviously, after pulling the fishing line out of the seal, I’m paying closer attention Is that a normal amount of oil expansion? It’s kind of got me thinking the drive might be overheating.
I have a drive shower on the boat, so unless a bearing is starting to fail, or the cone clutch is slipping. I wouldn’t think the drive would get that hot even though I’m running in 92° water and cruise at 3900-4k.
I’m gonna try and haul it this weekend to change the drive oil as it’s due in about 20 hours anyway. The oil in the bottle seems to be the typical level of dirty for 80 hours.
other than taking it to a dealer and having them throw dial indicators on the shaft or opening it up and inspecting the clutch, is there anything I should be looking out for besides metal flakes in the oil or it being excessively burnt for 80 hours?
