    50hp charging system

    I have a 2001 50hp merc (50ELPT) that does not charge the battery. I don't do a lot of merc repairs and was wondering if someone could help me out. I was checking the rectifier and it shows continuity on the two yellow wires in both directions, shouldn't it be in one direction only? The two...

    TD-20 cooling question

    Installing a tell-tale

    I am installing a tell-tell on a 1976 25hp Johnson, never done it on this small of an engine. My question is, can I drill and tap the thermostat cover above the by-pass and install the fitting there? By the cooling diagram in the manual it looks like it would work. Any thoughts?
