    Grinding Noise

    I would expect a "clunk" unless he moved the shifter at a snail's pace, not a grinding noise.

    The original is a 16-pitch prop, can I use a 15-pitch?

    A 15 will work for you. Only concern would be when lightly loaded the engine RPMs "might" exceed the recommended upper RPM limit for your engine. If that's the case, just reduce the throttle setting till they are within the correct range. You will notice better thrust at low speeds when...

    Grinding Noise

    You need to pull the prop and inspect the lower unit and front of the prop hub for damage. Only reason you should get the problem you mentioned is that the thrust washer is incorrect....as others have indicated....and the prop is rubbing against the engine housing.

    Prop Selection Advice

    Go to the prop sales/selection chart on the top of the site. Select your engine and then being a 2.3 gear ratio, I'd opt for a 15" pitch. The other details are provided once you select your engine for particulars. A quick check of 2.33 gear ratio, 5500 RPMs, 20% prop slip, 30 mph........Go...

    Does EFI solve the hard start/cranking issue?

    My boats sit for months at a time making fast initial starting a toss of a coin. Last year I installed an electric fuel pump proceeding my 2 stroke, carbed engine and it has helped my initial start after sitting come more quickly. On EFI you get the good with the bad... No doubt it's faster...

    Suzuki DF140a 4 Blade Prop

    I was running a 3 blade Laser II 20" SS prop and changed to a 19" SS Solace 4 blade. Anything requiring better prop to water contact was enhanced. Top end drop as a result of dropping 1" in pitch and adding the less efficient 4 vs 3 blade design only resulted in a drop from 47 to 45 MPH. Well...

    Talon SS Prop for 90 Vmax SHO?

    Most SS props are designed to highlight the benefits of modern propeller design and as a result will load your engine reducing RPMs but increasing speed. I would expect the 19 would be a good match for your rig since you published what a stock 19 will do. Boat reaction to the change in thrust...

    Bowriders that handle waves well?

    A co-worker bought an 18' closed bow Sea Ray with a 165 I/O and I drove it while on an outing one day many years ago. With Texas' usual high winds, and a large lake, the ride was very smooth.......and Sea Ray mono hulls I have seen fit the bill as I mentioned.

    Merc 2006 50 hp 2 stroke carb tubing size help

    I have an idea. They wanted you to buy OEM replacements from them so they hid the size.........OEMs do that you know.

    Identifying old SS OMC prop size

    I bought an OMC SST in 1973, their first sales year, for my 1972 new 18' tri-hull, bow rider, Caravelle with a 125 Johnson. I wanted a prop that I could use on Sunday and not have it in the shop on Monday with a bent blade and the price I paid was $185 plus Texas sales tax. I clearly...

    89' 90 H.P. 3 Cylinder 2 Stroke Battery Charging Issue

    Quoting from memory as my manuals are out in the shop, the rectifier/regulator uses AC power inputs from the stator's 2 yellow leads, both isolated from ground...battery -. The wires are: Yellow pair are AC input Grey is tach signal Black is ground Large diameter red is regulated 12v output to...

    Why don't you whack off a piece that isn't currently connected to a terminal (diameter stretched) and take it with you to an auto parts store.

    89' 90 H.P. 3 Cylinder 2 Stroke Battery Charging Issue

    If you have a black 9 amp stator you don't need a regulator/rectifier module. If you have a Red 16 amp stator, you need a regulator/rectifier module. The junction box was eliminated in later model engines like my 2002 90 triple with the red 16 amp stator with the regulator/rectifier and...

    Do older aluminum boats have the same issues with waterlogged foam?

    Back in about 1985 I bought a 1965 Alumacraft 18' Holiday I/O that had been sitting in a marina tied to a dock but the transom area was under water. I restored the boat and used the same white (moldy) Styrofoam bats that were in it originally and had enough structural integrity for me to hold...

    115 Pro XS Command Thrust on a pontoon - prop?

    My last prop purchase was a SS Solace 4 blade $275. Sometimes money isn't everything and that price for that prop and its performance is a bargain.

    Bowriders that handle waves well?

    Without reading other's comments, The deeper the V and heavier the boat, the softer the ride. Undesirable side effects: The longer to get on plane and the more HP required to propel the boat (with and without water toys in play) at a given speed. With that said and having had the same problem...

    Spark plug issue on 90 HP Mercury 2004 O\B 2 strike

    I ran the alternate gapped plug (in the service manual) in my 2002 90 and got better service. I suppose my boating habits were more suited to that plug than the SG. As I understand it, the SG stands up to lots of long runs at WOT. I ran them in a 1988 115 tower of power and they were a...
