what spark plug for protec motor

Thanks for the info on the wires. I may go to town and get the biggest (8.5) or more and see if I can get them to fit around the manifolds. Man, I basically have tomorrow to get the boat ready and I don't even have a carburetor!

Isn't vacation relaxing. Geeze!

Tim, I got new 764's today. Thanks for the reply on those. I will get them gapped correctly at .045. I am going to check the existing plug wires tomorrow. I replaced them at 850-900 hours. Probably a bit too long, but that's what I did. I leave for Minnesota on Friday so new plug wires aren't much of an option unless I can run automotive wires with dielectric grease in the boots. I am not opposed to that if it is ok.

Got my new carb today.....but as usaual it is the wrong damn carb!!! Nothing can go right with this floating turd. Hopefully I can get the new carb by friday. Leave Sat morning at 3a.m.

Thanks again for all your help Tim. Yes, I did bump the idle at GL. I just gave it a big turn before we got it in the lake. It is probably a bit high, but will deal with it till we get on the water.

Later.

What spark plug do I put in the 351 ProTec motor. I know it says in the manual, but I can't but those anymore so the store says.

I bought Autolite 24's but they don't fit in the head. Won't thread in. I bought a set from skidim an I think they were autolite 762 or something like that.

I am trying to troubleshoot many problems and this is a cheap thing to replace.

Also, I still have the original plug wires that came on the boat. I just ohm tested all of them and they range anywhere from 11-15 ohms. What is the specific rating of ohm's per foot of wire resistance????

I think these are good wires still and am going to swap out the PCM wires that are currently on it and put the originals back on just to see if that makes any difference.

Thanks for all your help!
