    2nd generation SDS Talon props

    The #2 cylinder was not firing. When plug wires were switched during a spark test, the #2 plug fired, and the one switched to did not. Next, I disconnected the wire sending power to the #2 coil and switched it with the wire sending power to the #1 coil. Again the #2 coil worked, sending a...

    Clean, add Carb Kit and adjust pilot screw on 1994 90TLRS

    After putting the kit into the carburetors, the manual says to start with an initial setting of 1 1/4 turns out for the pilot screws.

    My 18 year old engine still runs great. But I wonder if the oil injection sysyem may one day quit working. Since it is so old, would it be advisable to bypass it and pre-mix the fuel in the gas tank? Also,does 2-cycle mixed with ethanol gas go bad sooner in a tank than just straight ethgas...

    Merc 150 Overheat

    I was a guest on a boat powered by a couple merc 150s. The owner left the dock, revved up the engines to 3000 rpm and, after a short period, the starboard engine hot horn sounded. He slowed down. The telltale stream from this engine was weak in comparison to the port engine. The intake...

    Engine Surges at WOT

    My '94 90TLRS Yam 90HP just started surging at WOT. It runs fine at 46-4800 RPM. Recently, I pumped all the 2-month old ethanol-laden fuel out of the tank and replaced with fresh. That's when this started happening. Is this possibly a partially plugged screen at the tank pickup? If that's...

    Removing Inner Seal Without Damaging

    I have Bearing Buddies and use Spindo Seals. I do not dunk the hubs at the ramp. It's been a few years since I installed the bearings, and that's when I packed them thoroughly. Every year since, I've only repacked the outer bearing because I don't want to wreck the inner seal trying to remove...

    Thanks Rodbollt

    I am very grateful to you for your advice. I took your advice, popped the exhaust cover, and sure enough found a hole in the plate which was the cause of the water in my lowest cylinder. I was on the verge of putting my 90HP out to parts pasture, but I have a feeling it will be around for a...

    '94 Yamaha 90TLRS: Putting on a new head gasket. Lots of old gasket material stuck on head and cylinder mating surfaces. Someone told me to use 80 grit sandpaper to clean the block side(cylinder mating surfaces and related areas). Is this true? It sounds a bit coarse. Any suggestions other...

    Water on Spark Plug

    1994 Yamaha 90TLRS had water on the bottom plug. I found this when changing plugs today. What are the possible causes, and how do I trouble shoot? Other plugs were dry. Engine runs good, but has coughed and stopped a couple times recently when taking off from the dock after cold startup. Thanks.

    I have the new parts to fix my leaking seals. The rods are not pitted. I made a wrench to remove the caps, using a flat bar with four small bolts which protrude into the cap holes. Problem is that the thing won't budge. A mechanic told me to put a drift pin in one of the holes at an angle...
