    Bravo 3 overheating - oil expansion

    I believe I've assessed that my 2003 Bravo 3 drive with 1100 hours ( I've had engine and drive since new - so I know how she performs ) has an overheating issue. I've noticed that after running over 4000 rpm's that the drive oil reservoir level will rise considerably - even overflow over time...

    It's been a few seasons where the engine will either start on first turn of key, or it will take 3-5 attempts. She has 1030 hours with 95% of them at 3100 rpm's. And, taken care of well ! Recently chased down a gremlin that had me replace many of the sensors ( turned out be a loose dizzy ! )...

    DF 2.5 4 Stroke. Year 2013 - Mint condition. My question regarding the fuel shutoff -- when I store the engine, I turn the fuel shutoff to stop fuel flow letting the engine run and starve of fuel... She eventually stalls.

    SUZUKI DF 2.5 Remove Bracket Stopper

    I have a 2013 Suzuki 2.5 for a small sailboat. Can't tilt the engine up due to the plastic bracket stopper ( the preventer that does not allow you to tilt motor unless it is facing aft ) The motor bracket mounted to the boat is low so when engine is turned off and I want to tilt her, the...

    My boats windshield has a lot of water spots. Nothing! takes them off - no chemical and most hand-mechanical things.

    Need to install the serpentine pulley on a raw water pump for a 2003 5.7 freshwater cooled, closed system. I know there are some areas that need to be addressed - the Mercruiser shop manual seems to always be void of these types of important specifics. A few questions - what is the best...

    Bought a spare raw water pump for my 2003 5.7 MAG MPI Horizon that has the air pump fittings for pumping air into the system to purge raw water out ( a system I will not rely on as it has proven 'unreliable' ).

    Happy Holidays. I just pulled drive off to see that there was no O-ring to prevent water into the shifter ( both on the drive and the shifter cable/ boot side ). I'd love to say this was not my fault - but, no one works on this but me and, I've had this package since new - and, although I've...
