    1998 Mercury 150 2 stroke CDI replacement.

    How much is one of those replacements ? Recently inquired a CDI for a 2 stroke Merc 150HP EFI motor and almost fell from my desk's chair when the price appeared. Definitely will need to sell a kidney in order to purchase that costly electronic part or keep a stranded combo at terra firme...

    1972 evinrude 9.5 need long shaft or different trim?

    OK here's the deal : To understand, right now the water flow at speed is banging at the non edged lower leg portion (red line) when should be passing ideally under the yellow line right under the upper plate. That motor has a very tall gap between plates. Surely one will say that with that...

    1972 evinrude 9.5 need long shaft or different trim?

    With refference to my posted pic it's simply an awful height mismatch between an S motor and an S rib transom, the water flow was banging the X shown, shimmed right the combo now runs flawlessly at wot, a day/night water performance difference... To the OP, your posted video seems to show...

    Aggravating gasket

    I find that most if not all shade tree mechanics does sloppy works while saving money on parts that needs to be changed, second hand motors must be fully inspected from lower leg to top cowl as could turn out you bought a Pandora Motor. A carb is a mechanical component that must work...

    Next time removing the lower leg check the vertical water passage which delivers water upwards under the water pump's housing is free of salt layers which will reduce the amout of water intake being pumped upward thru the WP when at idle. If everytng checked is in excellent working order and...

    It's all about defining what Fun is for each individual with whichever boat/motor combo he's boating with. Don't need extremely costly combos to have fun with along associated free bragging with them. Almost anything that floats powered with a motor will suffice to have Fun.... Happy Boating

    is it to heavy

    It's all related about what you want to do and where you want to do it. OTOH, It's not the same boating with a 14 tinny with an underpowered motor for family oriented purposes compared to same tinny powered with a larger 20-25 HP motor and 4 grown ups. Fast displacement speed is extremely...

    1972 evinrude 9.5 need long shaft or different trim?

    All HP motors are different, doesn't matter if being same brand, that's why some needs to be height fine tuned to cancel any water plashes out/over transom. Need to water test as suggested the new motor height, dry boating means nothing. LOL!! Happy Boating

    Your Worst Nightmare.-

    To avoid breaking salt seized factory delivered bolts, now installing next hardened, superior quality ones.

    You're welcome. As several parts have been replaced including new poppet valve, t-stats proper time to check, clean, replace both temp sensors specially if that 20 year old motor has been running on Florida's salted waters for that long. No one checks, cleans them as a preventive maintenance...
