Yeah, I'm guilty as hell on that one...you had it right the 1st time...

Congrats on the wet test. My puter done died. I just got the laptop fired up. I saw the other thread. Sits high in the water. If the bottom is rough it could cause a bit of turbulence. I would love to see a picture of the stern with neutral trim kinda rifling the cav plate or the keel. Too high by 3/4" ? Which mount hole did you go with? Hot rod..:clap:

I dropped it one notch, then another notch and still runs hot...having found some sand in one of the t'stat housings, I'm starting to think there's more in there clogging up the works...Spare is thinking it may be the new water pump we put in when we mounted the Johnnie...not genuine OMC/BRP parts I don't disagree it may be the culprit...we're workin' thru it and WILL figure it out...
Ridge, yer not the 1st person to note how rough the bottom of this boat is in considering the cause of this over heating issue...never woulda thought it...

Reel, remember the Merc 150 that was on my V when I got it? It was doing the same thing and was FULL of sand. Take off the lower and go to town with a rubber hammer.

Like said above, we're gonna be pulling the lower to install a new water pump...I'll take you up on the rubber hammer suggestion and raise you a power hose to boot!!...when we bolt this thing back together, there AIN'T gonna be any sand in it...ANYWHERE...thanks for the suggestion!!...:clap:

I know it will get figured out. If the motor was mounted on the verge height wise, the bottom could be the culprit. I was suggesting that only 3/4" high (one hole on the bracket) probably wouldn't be the cause, rough bottom or not.
The bottom will have its day. Don't sweat it.
I got a new impeller for a Yamaha 80 hp and it was the wrong one. It had a slightly smaller diameter and didn't fill the housing enough to get any flow to the powerhead. Not saying that is what you got, just remembering what a PITA it was to do the job twice with two trips to the dealer. I feel your pain.

Do you have the correct tube for the water pump for the 25 inch leg? A mechanic installed the wrong one on one of my previous engines.

We'll check it when we drop the foot for the pump change...good idea...

hey Reel, you being quiet or what
:thre:

Let the cat out da bag brother.
