    Source for power trim switch on older Evinrudes?

    momentary single pole double trhow switches are made in all sizes ( maybe not yours exactly) maybe you can fit something close enough search AMazon MC MAster etc.....

    Impeller replacement schedule

    Agree... some stuff is cheap but....I can't say that I have yet to read that many horror stories of impeller causing catastrophic damages, after reading thousands.... posts from 3-4 sites across 20 years . But I agree yes...horror stories do happen ...from neglect more likely...

    Impeller replacement schedule

    Dry runs in the driveway probably kill more impellers than years of looking for fish. my 75 ETEC probably has had 3 impellers in 17 years and all looked fine when replaced... did them anyway to be safe .an ounce of prevention is worth a pound of cure :-)

    Impeller replacement schedule

    all depends on hours/year of use & the quality of the impeller I have seen some lasting 10 years + but to be safe 5 years sounds a good mid point. Some swear by 3 years . This should be an interesting thread.....

    Setting points on 50's-70's Evinrudes with a meter

    I notice the Honeytek works on a 9v battery. Unless the meter has a built in voltage booster to reach 275-300 DC which I doubt it would be incapable of testing an outboard capacitor in a simulated mode of operation. it may tell you a uf value or a dead capacitor but it woul be unable to...

    Setting points on 50's-70's Evinrudes with a meter

    basic VOM style meters with capacitance will give you the capacitance value (if not open or shorted) using an internal meter battery of maybe... 9v you did not tell us what meter you purchased . Testing capacitance at 9V will not test the capacitor's tolerance to high voltage kicks...

    jack plate wiring

    great now buy some relays and hook it up properly so you don't make needless sparks and blow something expensive !

    Setting points on 50's-70's Evinrudes with a meter

    throttle position is not important no matter where the throttle position is at.......... the points/will always begin to open when the piston reaches TDC . just follow this video and all will be fine. the high point of the cam lobe will just....open the points at TDC if adjusted per...

    jack plate wiring

    relays are there to carry high current loads that common switches can't otherwise the arcing will eventually burn the contacts or worst...weld them shut relays allow you to control the transfer of these high currents without looping to/back from console switch positions. you need...

    Evinrude 2hp Issues

    sparks tested ok but.... after a while sometimes the capacitor or coil can start to act funny. Unless you have a proven good capacitor assume it needs to go ...and replaced. inspect the coil for burn marks . best yet take everything apart (mag plate) and change the pulg wire with a new...

    70 hp rectifier wiring

    btw... if your 40-50-70 $$$ rectifier goes bust the littles square one properly mounted should do an excellent job for a few $$$ they accept two yellows on the AC pins with one + V out pin and one GRD pin to hook=up on the engine frame rated 25 amps ...

    70 hp rectifier wiring

    exactly ! 2&3 are bridged if the 2nd yellow/gray is to reach the rectifier dual yellow inputs ! this is done internally by design of the terminal block or with clips joining both screws. has requested by Racerone.... PICS are needed here

    70 hp rectifier wiring

    In this other version of a 1980 engine you can see the 2 yellows feeding a rectifier whose output (RED) works it's way back up to join up on the solenoid/battery wire. The above posted JPGs do not show this very clearly because the red output takes a different path but the end result...

    70 hp rectifier wiring

    the rectifier ouput must reach the solenoid to pass it's output voltage and current to charge the battery... can't address your issue but find out why the rectifier is not connected to the solenoid post where the batt +12 is connected.

    70 hp rectifier wiring

    THe 2 yellows are AC voltage from above (flywheel) the 2 AC go on the 2 AC pins of the rectifier or need to match up with 2 yellows FROM the rectifier... the RED has stated... comes from the starter solenoid BATTERY SIDE NOT the STARTER SIDE.... and is connected to the DC outpout of...
