Im chasing a high speed overheat and wanted to get your guys opinion on these manifolds. Are they bad enough to cause a high speed overheat?
Thanks,
James
Hi all!
I have a 351w mercruiser that I am having some trouble with. Late last year it was starting to have a high speed over heat problem so I just put it away for the year and I was going to deal with it this year. So taking the advice on the forums I did the following:

Hi all!
I have a 1975 20 foot Webbcraft runabout. I have a 233hp (351w) mercruiser with 1.32:1 geared out drive. Manual states WOT RPM is 3800-4200. This is my first I/O boat so this is all new to me. I have an aluminum prop that is 19 pitch and 16 inch diameter.
My problem is it takes a...
Hi all,
So I replaced the impeller with a kit that came with a new housing and all that jazz. I took the lower unit off along with the drive shaft case. Got done with the rebuild and mated the two together. I made sure the intermediate shift shaft was pointed toward the front of the boat while...
Hi all,
So I took a garden hose to all the hoses on the engine and I got good flow back out of the corresponding exhaust hose. (Good flow being defined as filling the diameter of the hose and making me soaking wet.) I also took off the thermostat housing cover and there was no thermostat in...
Hi guys just bought this boat took it out, works pretty good. Noticed that the temp gauge was just ever so slightly in the red zone. So I shut her off let her cool down then took her home. I am getting water out of the ports by the transom on muffs. But I decided to pull the lower unit and take...
Hi all!
I have a 1969 55hp evinrude. I have started to re wire it as the old harness was trashed. So I started with the ignition circuit. The amplifier box was shot so I decided to do an HEI module conversion. I use the points to trigger the HEI Module which then in turns breaks continuity to...
Hi all!
I just bought a boat, trailer, and motor for 50 bucks. The image you have in your head is probably pretty close to what this thing looks like. I basically bought it for the motor. The motor model number is 55973A.
So my dilemma is this, the wiring on this motor is shot; it?s one of...
1975 85hp Johnson.
Model: 85ESL75E
Put a generic full bridge rectifier on, wired it up correctly, and checked voltage at battery.
not running= 12.68volts
running= 3.5-12.80 volts
then when I stop the motor after a few minutes the battery shows 12.73 volts
So the net result is the battery...

Model: 85ESL75E
The battery is only displaying the battery voltage of 12.6v when running or not. The motor runs great. I have a service manual, so i decided to look at the rectifier first. I did a quick test.
I took the negative MM lead to ground, then went to wire...

So i bought this motor from a guy that said it was ready to hit the water everything was fine. I ran it on muffs and saw water coming out the thermostat exhaust ports and thought i was golden.
I took it out that Saturday floored it and 50 yards later the...
Re: Scott-McCulloch 3.6 Not Pumping Water
Hey guys thanks so much for the help. I think I have it inserted right, I just don't know whats wrong perhaps is just worn in certain places?
To better show what I have going on, I took a video. Maybe you guys can catch something that I'm missing...
I have a Wizard 3.6 hp made by Scott-McCulloch. I recently got it running and it runs pretty good just doesn?t pump water. I took the lower unit apart and the Rotor type pump looks old but still intact, the little leg is still there and it seems to make contact with the sides. So then I took...
I have a 1960 Evinrude lark 2 40 hp
I took a video of what I?m experiencing which I think might help describe my problem better than anything I can write. The audio is not good but every time you see the engine shake it like cuts out and it not throttle up it will die.
