Yeah, I took the oem spark plug to autozone and they said this was the compatible replacement… one of the E3 spark plugs I guess. These had less than 40 hrs on them. Lesson learned. Only NGK IZFR5G...

Well, seems like those spark plugs were the issue. Pulled out these and replaced with the correct plugs at .032. No sputtering now. 468307468308468309
Thanks! My NGK IZFR5G plugs are on their way. I've read that 20ftlb is the correct torque? But I can't seem to find the correct gap. Will I need to adjust gap for the optimax?
I am at 83.7 hrs now. Thanks
Hey Butch, I consider myself somewhat handy... But is injector servicing and reed replacement difficult or do I need specialty parts or a DDT at any point?
Thanks Butch. I saw another thread that mentioned the reeds. I’ll take a look. Thanks!
Thanks Phil. I was wondering if it was a bulb priming issue also. But it seems to do this both if it’s primed or not. And I’m going to get the correct plugs… I shouldn’t have rushed and got what was...
2012 150hp Mercury Optimax 2 stroke. Serial number 1B934227
You all have been invaluable and I'm needing help once again. I bought this at the beginning of the season with only 40 hrs on it (I...
All fixed. Went out today and no overheating. Temps stayed down! :)
Retest... Idle around 500rpm temps slowly rise to 151-153. No drop in coolant temp during this. But when I increased rpm above 11-1200rpm, temps dropped to 120's. When I slowed rpm back to idle...
Ah... I understand. This is coolant temp, correct?

I can't say that I noted a sudden drop in temp while it was warming up... During idle, it climbed slowly to 151 and stayed. When I tested...
Thanks Phil.
1. I pulled up the mercury part list and it seems as though part number 1 pulled away from part number 2. There was no crack per say, but the seam pulled apart here. I cleaned it...
Thanks, makes sense. I’m still learning how each bit works. I got it together fine and tested and seems to be running fine. I forgot to put the silicone in though, so I’m going to take back apart and...
Perfect. Thanks.
Two more Q’s:
1. Do I need to re-grease here at the base (see pick with old grease)

***EDIT*** it seems as though my base has separated here (the following is...
My water pump kit arrives today and I’m preparing. Quick questions…
I know I apply high temp silicone here (A), but there was also silicone at (B) during disassembly. Do I also apply at (B)?

Glad to hear that! I had heard others report impeller fins broken off etc, so I wasn’t sure. And yep, I ordered the whole kit. And thank u for doing the write up on how to replace. Very very helpful!
Parts still on their way… but I couldn’t wait, so I removed the old pump. I am somewhat concerned now tho, as the old impeller looks ok? Gaskets seemed intact. Does this raise suspicion re other...
Thanks and absolutely. Pump is on its way. :thumb up2:
Well, I’m glad I’m not the first!
Oh my… wow, well I definitely don’t want to make a simple problem into a huge problem. Thanks for that!
Awesome. I don’t mean for you to do the extra work for me. But I really do appreciate the info. I’ve read thru the fuel line one previously but hadn’t seen the others. Thank you!!
Thanks for the reply. I bought this at the beginning of the season. It only had 45 hrs on it, but being a 2012, that meant a lot of sitting. I absolutely suspect that the water pump hasn’t been...
Ummm yeah… I was checking my thermostats on the water and a big storm rolled up. It was sitting on part of my boat cover. Wind must of caught it and in the water it went. I didn’t realize until I...
After checking the thermostats today, I took the boat back out to see if I could gather more info. I did find that the boat sure loves WOT. No problems when I’m running full speed. Temp stays around...
This is going to sound crazy, but I lost the top plastic cover that attaches to the motor under the cowl. Until I buy a replacement, is it ok to run the engine?

I took out the thermostats. They look decent. They opened up around 140 degrees.

I sure hate to take off the lower unit to examine the impeller if that’s not the issue. Any other steps...
