Good evening,
First – I have tried to look at the other postings on Bravo 3 Outdrives for similar items and reviewed what I found. Not finding one that matched – if I missed one, I’ll apologize in advance if this is duplicated.
Summary of my normal maintenance – boat is stored inside storage with full fuel tanks over winter. Oil changed and gear lube replaced last fall as well as new batteries this spring (Optima Blue top). 2009 496 Mag with Bravo 3 OD with about 80 hours on it.
Last fall, we used it right to end of season – and the marina pulled it before I got there on Saturday, and racked it away into heated indoor storage. They said they filled the fuel tank and Stablized it (cannot verify).
This spring she had a hard time starting and ran really ragged. Excessive vibration shook the entire boat (love watching the forward deck bounce up and down – not!). Once warm – this goes away not to return until next cold start.
Last outing was perfect. Tonight – really hesitated until really warm – bad fuel? Would not get on plane for repeated attempts until nearly half hour. Then another new experience – nearing higher end (35mph or higher load) would hear clunking sounds coming from the engine/OD. Difficult to identify exact location while driving. At dock – I revved the throttle idle and received no similar sounds.
Summary of issue:
Running rich - nearly double gph burn
hesitating
vibration
clunking noise nearing top end
no WOT
Horrible acceleration
So – discussing with dockhands – first off I’ll add octane booster and see if that helps. Fuel degradation could indeed be an issue. Next, perhaps some fuel stabilizer since it sometimes is a week or two between uses.
Thought I might have my mechanic take a look – since he did the gear lube.
What’s your ideas on other items to consider?
Thank you,
-Dennis
