Hello everyone. New to the site and first time posting here. I live in Michigan and own 1993 K18 Kayot with the 4.3L Mercruiser Alpha One with Thunderbolt IV ignition. Purchased this boat last summer with zero maintenance records but it's fairly clean. Only thing I've done is changed the starter to a marine grade (when it died first time out lol) and put new tires on the trailer. That starter fact leaves me a little weary on the general upkeep and maintenance if any was done previously to the engine.
I've taken her out about 12 times total and only for about an hour of run time in each session, so managed to go through one tank of gas over the last 2 seasons. I always use additives and add stabilizers at end of the year, along with anti-freeze and fogging oil. She's already down the road and in the barn for the winter.
Now this year she's had some trouble re-starting after doing about 20 minutes around the lake and getting nice and hot. I've noticed I've had better luck restarting when I have the neutral throttle barely bumped forward. I keep thinking it could be vapor locked but I keep forgetting to bring the starter fluid to test this theory. But then again I didn't have this problem before, so I really need to do some general maintenance.
I'm searching for part numbers on:
Plugs
Wires
Cap
Rotor
Impeller
Gear lube the outdrive - how many ounces of gear lube does this take and what are the replacement o rings/gaskets for drain plugs
Change engine oil
Fuel pump
Fuel filter or water separator?
If anyone can chime in with a service manual or the correct part numbers for these that would be much appreciated. I've heard good things about Quicksilver replacement parts. I've also seen bundles of tune up parts like plugs wires cap and rotor from Quicksilver for around 90.00$. Just want to make sure I get the right parts.
Thanks again! I'd post a picture but apparently im not authorized...
