Question about Boating

2 Answers

I have a 150 hp outboard Mercury that is carburated. It has not been ran in more than a year. Boat had quit on the lake last April. Found bad starter. Had rebuilt. Put back on and was able to start in yard and run. Two weeks later would not start. Replaced fuel filter, primer hose setup. Just found safety switch in off position. Thought I had it but will not start. Have insured that fuel is getting to the carbs. Where do I go next.

Part of the problem was apparently of my own making. Number one, have to remember to check the safety switch located right below the throttle area. The toggle was kicked to the OFF position. May have hit it while wiping down the console in preperation for taking to the water. Once I found the problem, still had an issue with getting gas to the carbs. I pulled the quick connect of the primer system off where it connects to the engine and had to bleed multiple times to get air out and could see gas coming through the glass filter cleanly. Boat started on the second time over. Just like always did for me. Took to lake and runs fine now.

Did you put a fuel stabilizer in when you laid up the engine. If not varnish will build up in the system and clog the needle valves and jets. Use a good carb and injector cleaner to clear the jets.

Speedometer not working my boat

Unless that has a spin wheel sensor on the transomn, you will find your pito tube intake is plugged. Most common on shallow water boats and weedy lakes. Using a wire and some compressed air on the pito tube (NOT the gauge) will usually clear it, but get ready to keep cleaning it as that was the nature of the beast.

Most of those big mercury motors had the pick up built into the lower unit.
