    Tach question

    After replacing the recitifer the tach started working. BUT when the power is turned on to the tach it jumps around 200 rpm when the engine is not running. Is this an indication that the wrong setting is being used? I set it on the 6 position. When going wot the reading seems to max out at 6000...

    High voltage

    Does the original Merc rectifier have a regulator in it? I replaced the original with a radio shack item and after installing a voltmeter I read high voltages. The newly installed voltmeter is fairly accurate and agrees with a digital meter reading voltages at the battery. What happens is that...

    1986 Merc 60hp 3cyl Tach question

    Tach does not work and for a good reason. Wires cut off about 3 inches from back of tach. Maybe its junk but need to test it. It is an OMC with the numbers 173604 printed on a sticker on the back. There is a 5 position switch with the settings of H, 6, 4, 3, 2. Set it on 3 for 3 cyl? The wire...

    Setting maximum spark advance question.

    86 merc 3 cyl 60 hp The manual says to put engine in a test tank or if mounted on the boat to put in the water for setting the max spark advance. Is a test tank something more than a 30 gal garbage can? That's all I've got for now. The engine is mounted on the boat so figured I would put...

    Telltale Experience

    From my "What Now" thread, I got the engine running. So I thought it time to check the water cooling. Borrowed the neighbors muffs and gave it a test. There was water out the center of the prop and a sputtering out two rectangular holes just below the power head in the aft of the engine, but...

    Info help on motor

Checked the compression 60 and 75 even after a squirt of oil. Put in some strarting fluid and put plugs back in...

    Progress with this Merc

    Bought my first boat back in Feb. It has a 1986 60 hp 3cyl engine. Seller said it was having fuel issues. Also needed the starter drive gear. Got the gear from iboats and got it on today. Did a compression test and all four cylinders were around 140 psi. Had spark on all three plugs, so seller...

    1990 90hp Force

    Asking a question for a friend. He has a 1990 90hp 3 cyl Force engine. S/N 908F90B. In the recent past he switched out all the electrical engine wiring from a parts engine. Was able to start the engine after making the switch. Ran for only a short moment (guessing 10 seconds) and was turned off...

Been trying to determine by comparing parts on iboat but that is confusing and very time consuming...
