is this normal?

[nigelbear]

My tail shaft housing gets hot enough to evaporate water that splashes up. The water comes out in good amounts and is also very hot. Should I be worried about overheating? Is here something wrong? I posted this question once but now I can't find it on the forum. Thanks for your insight in advance.

May have some leaky inner exhast housing seals ,but without knowing what engine is in question or whether it is a thru hub exhaust engine, it is just a shot in the dark.if water exiting engine is too hot to touch you most definately have a problem.Check T/stats and let us know when the last waterpump was installed.

It does not sound a little too hot, it sounds way too hot. Charlie

Here's your original post. <br /><br />I've got a later 28hp, which is based off (read rebadge) of the '50s 25hp. None of the cooling water is sent down the exhaust part of the exhaust tube - it all comes out the large hole on the back of the exhaust tube. Some water ends up coming out the exhaust, but it's introduced somewhere around the waterpump.<br />To make a long story short; if it's set up like mine, the exhaust tube gets very hot, enough to burn the paint slightly. I've been thinking about changing this on mine since it's getting a new paint job.

it is a 1957 35 horse evinrude. it does not have thru hub exhaust. the impeller is new and shoots water out pretty good at wot and idle.

What exactly are you planning to change?

Pretty major surgery directly below the powerhead, in the exahust tube seems to be the ticket. I'd have to partially block the current water outlet, and cut back (or drill through) some of the webbing between the current water outlet and the exhaust sections. The trick will be getting the water to where it's needed (pretty far towards the driveshaft) and keeping it out of the bottom cylinder (the exhaust ports are pretty close.)<br />I still haven't decided how to do this exactly. I wouldn't mind some input on how later engines were setup. Or just plain old opinions would be nice.
