Is it normal for the exhaust/foot portion of motor to get hot on muffs?

[Bass_boy7]

Hey guys I was wondering if this is normal for a 1969 johnson 115 when running on the muffs b/c of the lack of water flow? when I say foot of motor I mean the exhaust portion of it not the actual gear case, the water was coming out of the two exhaust holes so I know there was water getting around the engine and the water was Hot, but I used the lower portion to help me stand up haha and to my surpise it was hot is this ok? I didn't really notice this before to be honest this is a new to me motor so I want to make sure before I take out on the water this weeknd thanks guys.

That portion of the engine is usually under water, I guess it could get a little warm when on the muffs.

yea just set me back bc I touched it like I said to stand up and it was hot I didn't think it would get hot so I guess thats true when under the water it might be cooler and the more water flow through the water intakes would help greatly with the heat disapation. I know my house hose is weaker so not a huge amount of water gets into my motor when it runs is this ok to do for like 5 mins or less a couple times a week?

To check the block for overheating, remove the cowel and hold your hand on the cylinder head. You should be able to hold your hand on the cylinder head for 2 or 3 seconds, it will be warm but not warm enough to make you remove your hand.

yes I can hold it for 2-3 seconds but then I must remove my hand after that because it gets hot, is that ok?

Sounds ok, but you could always get one of those cheap laser temp guns to double check.

yea like I said my house water pressure is weaker then most unfortunately so I assume thats the reason why it doesn't get all the water is should be getting, I even hold the muffs onto it tight with my hands and block all water drain holes etc to try and get the most water up to the pump, it takes a bit but then the water begins to come out those two exhaust holes but it doesn't come out of those holes for the first 30 secs-min I hope I didn't fry my motor by doing this I don't think I did bc it runs fine

It normally takes a little time for the water to come out of the exhaust ports.
You could always install a tell-tale kit to make sure the water pump is pumping water.

they sell kits like that? I really would like one, where could I get my hands on something like that and how does one install it?

I kinda put my own kit togeater, try a search and I am sure you will find the info you need.

alright thanks I will have to look into that, so guess my motors fine then? The lack of water pressure is probably my culprit?
