    Alpha one gen 2 tapping at hard turning angle

    Same u-joints. Tilt or turn doesn't matter, same forces of misalignment are on u-joints & gimbal bearing.

    1971 Larson GM 250 Inline 6 165 HP

    Fresh or salt water? Salt water is probably a corroded manifold & riser. The manifold with the removable top portion went away with early 1970 160 hp models. All 165 models had the 1 piece manifold.(assuming some DIYer didn't retrofit an earlier manifilold). You replaced the water pump...

    Mercruser outdrive

    Your question lacks any detail. 1960s, 1980s, 2000s vintage? Mercruiser Model 0, #1, #2, #3, TR, TRS, Alpha, Bravo? If you are familiar, by looking at it (although the R/MR/Alpha gen 1 can deceive). Serial number?

    Question for Kevinj & Racer

    Regarding low oil alarm, apparently the oil quantity was lower than I was lead to believe (I never checked for myself) thus setting off alarm. Topped off tank & all alarms silenced. But why was it constant with engine off? IDK Factory manual does not say. BUT.... It does say to test vacuum...

    Question for Kevinj & Racer

    So follow-up/resolution: Replaced VRO & vapor pump. Oil useage & smoke decreased but still get high vacuum alarm & surging at higher RPM. Since replacing VRO requires running off premix during alarm testing, purging oil lines & verifying oil pump funtion I was running off a 6 gallon tank thus...

    1996 Evinrude Intruder 150 - Runs great on muffs, dies in water

    Actually, fast start is activated when key is in crank position regardless of engine temp AND also when ever engine temp is below I think 105 degrees. So even a warm engine will get the timing bump during start up.

    1993 Evinrude 50 hp. Missing water tube .

    Because AI is AI & not that of an experienced old guy. Earlier motors used a copper tube, I'm not sure of the cut over year.

    Gear Oil Leak - What is the Cause

    If I recall correctly, some Bravos use the plastic model too.

    Gear Oil Leak - What is the Cause

    I put S/N in search & got conventional, digital & Delco EST choices. The conventional is this oddball Prestolite system. Here is the picture, looks like ghosts Ebay link.
