    Yamaha 25 HP - Adding Rectifier. What kind of battery do I need?

    I'm adding a rectifier to my 25HP manual start Yamaha. I will only be using the battery for a fish locator and marine radio. What kind of battery should I use? Can I use a cranking (starting) battery vs Deep Cycle?

    1974 25HP Johnson - timing/Points. Lose 1 cylinder after long run

    I changed the plugs, points & condenser on my 1974 25 HP Johnson. Starts right up. Trolls great, idles perfectly. But if I run the engine wide open for longer than ~5 minutes then slow down I totally lose 1 cylinder. I set the points (per spec) at .022. Plugs (J4C's) gaped to spec .030...

    Johnson 25 HP 1974 (25r74m) - Screw stripped Cylinder to Crankcase

    So the new cylinder and crankcase I bought from Marine Engine has a bad bolt hole that attaches the cylinder to the crankcase. When I went to tighten the bolt (using a foot pounds torque wrench) an outer bolt hole (it's not on one of the ends) will not tighten. Is this a problem? All of the...

    Johnson 25 HP 1974 (25r74m) - Connecting Rod (Flat spot)

    Good? I didn't realize there was an adjustment on the coil. I thought the bolts automatically aligned it (so thank you...!!!). I took multiple pictures of the location of the old one then took a sharpy to mark where the old one was at. hopefully it's accurate.

    Johnson 25 HP 1974 (25r74m) - Connecting Rod (Flat spot)

    There is a flat side on the connecting rod that connects to the wrist pin. Does it matter which side of the block the flat side goes (intake or exhaust)? I'm rebuilding my first outboard and didn't notice the flat spot on the connecting rod when I took the connecting rod off the piston. Thank...
