    Cylinder Compression Incongruences.-

    Yep didn't mentioned it before, the shirt was beginning to lightly scuff on pistons and rings as well, was seen when turning the cranckcase upside down. That's why was sent back to the machine shop to have it properly honed as the moron techie didn't do his work right probably due to having...

    Combustion Problem?

    Never have seen a carb so gunked that was impossible to be cleaned to perfection. This carb was one step before being thrown into the deep blue. After an overnight soak in lacquer thinner and a meticulous manual clean up was fully recovered to work flawlessly. If still having gunked fuel...

    Cylinder Compression Incongruences.-

    What can I say, seems the cylinder sleeves internal gap were bored too darn tight to work adequately with 2 new OEM standard piston and piston/rings, keep in mind that the mating surface of the cylinder head was shaved even as was darn pitted and corroded and a new gasket wasn't going to sit...

    Unable to start and no water out the telltale

    To clarify my previous post with pics. If after changing impeller, thermostat the motor starts but overheats, smokes through the tell-tale, with no water being peed t's a clear indication that said motor surely has internal scale build ups inside the crankcase's water passages regardless of the...

    Suzuki DF25A prop

    So for my particular boating needs you'll recommend me to buy 3 alike 8.2 x 8.5/ 3 blade alum props and pick the one that revs best and throw money into the deep blue for the rest 2 ? Surely will turn into an extremely out of this world expensive recommendation. In real boating world no one...

    Suzuki DF25A prop

    The issue with props is that the diameter it's whatever the prop manufacturer wants to play with, pitch is what makes the motor to rev higher or lower, diam is secondary. As the pitch size increases/decreases so does the diameter. Happy Boating

    Unable to start and no water out the telltale

    Bought many moons back a second hand 96 Evi 15 HP in super mint external and internal condition. As I like running wot powering light applications, next day begun behaving exact same as yours. Cleaned lower leg's water intake screens, changed impeller and thermostar with no avail, the isuue...

    Combustion Problem?

    If starter fluid or pure gasoline can't make its way through the carb into the combustion chamber to check internal combustion, remove both plugs, inject a shot of starter fluid or pure gasoine inside, install plugs back in, start the motor and check what happens ? Belt timing doesn't go wrong...

    Cylinder Compression Incongruences.-

    Wondered exact same, definitely the moron machine shop techie forgot to hone both cylinders assuming were bored and honed to factory specs after installing 2 new cylinder sleeves. it's the last straw that one has problems associated with work not done correctly by others who are supposed to...

    Unable to start and no water out the telltale

    Up so far, after the water pump, the carb has been rebuilt, the fuel pump, spark plugs and thermostat has been replaced, did the motor started flawlessly or still with same previous issues ? Don't need to run a motor just on salt water to achieve reduced salted water passages, fresh water...

    Suzuki DF25A prop

    What does an OEM Suzuki prop to do with an OEM OMC one, different brand motors and props. Suzuki does states manufacturung 7 to 11 pitch props for said motor being the 10 the standard factory delivered one. But if being too darn costly compared to a non OEM one way to go saving some cash and...

    Combustion Problem?

    If the motor is hard to start specially when cold say first morning start surely 60 PSI seems way low, if squirting oil into the each cylinder does the compression rises ? Paul surely has the cylinder compression chart for said motor... Happy Boating

    Cylinder Compression Incongruences.-

    Updates : The crankcase was re opened for a second time, having 130 PSi cylinder compression was too much, although the motor started right up the rope was very hard to pull. The machine shop polished both cylinders and now with 120 PSI on both, much softer to rope pull than before. After only...

    Suzuki DF25A prop

    Why is it that everybody is installing non OEM props when going for a prop maximization when OEM Suzuki ones performs top, these guys knows well their prop business. If the motor is currently revving at 5300 wot revs, is revving at 700 rpm less from its max 6 K range, an alum 3 blade 9 pitch...

    Tried everything, except what's really wrong.

    Is the ground terminal of each electrical component included where it screws at the crankcase impeccably shinny clean? To check if the fuel ignites properly : Remove both spark plugs, squirt a small dose of fuel indide each combustion chamber, put plugs back in, prime the fuel bulb till fully...

    tell tale

    An inpeller housed inside a water pump which rotates elliptically with vanes expanding and compressing at opposite sides will suck water upwards while the motor is being flushed ON in a barrel or on muffs. How much water is being sucked will depend entirely on the impeller and liner condition...
