    Water Pump Failure

    That pump was run dry. The white pump housing was melted by heat from friction. The impeller also got heated. The good news is that it looks like no parts of the impeller or pump housing got into the water passages in the engine. I have seen the exact same thing before. The water level at a...

    engine height 2120SC , F150

    I have the 2120 sport cabin with the F150. Motor bolts are in the second hole from the top. Performance is just about what Yamaha shows on their tests with wide open at 5400-5500 rpm with either the 13 3/4 X 17 prop or the 14 1/4 X 16. Max rpm for the engine is 6000. Has anyone with the 2120...

    2120 with Yamaha 150 4 stroke

    What prop are you turning? You are somewhat lugging the engine as the range is 5000 to 6000rpms. The closer to 6000 the better. With the engine trimmed and tabs retracted I turn 5500rpms and 38mph. Just about the same results with the 13 3/4 X 17, 14 1/4 X 16 and 15 1/4 X 15 props. Search my...

    Where to locate sonar transducer on Parker 2120

    I have two airmar inhull ( shoot through the hull ) transducers for a Navman digital depth finder and one for a colored fish finder. Both are on at the same time and I never have had a problem with readings at any speed including wide open. I got rid of the transome mounted transducer because...

    cheap spark plugs

    Was headed to my local marine shop to pick up plugs for the F150 which takes NGK 6376 LFR5A-11. Decided to stop at an AID auto store along the way. They do not stock that plug locally but their main warehouse does. Had to buy a box of 10 which was delivered to the local store the next day at...

    F150 gear chatter

    grouperjim, all is well. Called Yamaha tech services down in Georgia and they said there is no problem running it in gear. Just make sure no one can get hurt. The noise is caused by the heavy steel prop causing a drop in rpms when you first put it in gear allowing the shaft to chatter in the...

    F150 gear chatter

    neither the owners manual or shop manual has any warning about puting the engine in gear when out of the water. That said I don't think its a good idea for safety reasons to do it for any length of time. I do it to check the shifting and only have it in gear for a few seconds and make sure no...

    2120SC w/F150 Yamaha gets water under cowling....HELP!

    This may sound nuts but taste the water...is it salt or fresh. I assume you wash down the motor after each use and I suspect the water is from the air intake Ray

    F150 gear chatter

    I started up my F150 after winter storage using ear muffs for cooling. Started right up with a good stream out the tell tale hole. I noticed what can be best described as a clicking or chatter from the lower unit when I briefly put it in gear to test the shifting. It is not gear grinding and...

    Yamaha F150 on 2120SC Water Under Cowling

    Anthony, that bulletin was 02006-004 Yes a small portion ( couple of inches ) of the gasket will lift off easily especially if you don't lift the cowling straight up. Ray

    Yamaha F150 on 2120SC Water Under Cowling

    Anthony, I assume you checked the cowling gasket and that it is seated properly and the two latches snug it up. At the top inside of the cowling there is a series of baffles that drain out any water that may enter the air intake down through two hoses. The problem is that on certain year...
