    Spark Plugs

    03 VMax 150 is starting to act up this year. WOT with JP at max/full trim, motor looses power and sounds like a miss in the engine until I fully stop, turn off the motor and restart, then everything is fine. Random occurances, 3 times so far this season. I've pulled the plugs twice and they all...

    Intermitant loss of power

    03 150 Vmax flutters and skips when trying to bring up onto plane first thing in the mourning. I have found that if I turn off the engine and restart, the problem will resolve itself. Anyone have any ideas on what I could look for. Thanks....

    Shop manual Specs

    I have a V150TLRB and ordered the shop manual last year for the engine. The manual does not cover my specific model, but has multiple 150 HP motors with different specs for each model. It covers C150X,150X,S150X,L150X,P150X, and D150X. Can anyone tell me if one of these will cover my motor. I...

    Thinking of changing to a smaller prop diameter

    Hi all,<br /> I am running a Rapture 14.25 x 25 SS prop on my Yamaha 150 which turns around 5200 WOT (62 MPH GPS) and I'm looking at a Yamaha 13 3/8 x 25. My question is, will the smaller diameter prop get me to a higher RPM range and possibly more speed? I'd like to run my motor at 5500...

    I lost 2 cylinders in my 150 Vmax due to water ingestion and had to have the motor rebuilt. Yamaha would not cover the engine and I had to go the insurance route. Just got the boat back last week after taking my boat to a 5 star rated Yamaha dealer in the local area. After running the motor a...

    Where can I look for water blockages??

    I took a look at my Water pump yesterday (03 VMax 150 Carb Model)because of low water pressure last season (on the gauge and peehole). It was fried...and melted in places, so I replaced the housing and impeller along with new seals and coller. Water pressure did increase some, but not as nearly...
