Exhaust Hose Fried

Thanks that is what I did, but with a shorty screw driver and by touch....What a fit, I did not have the option of removing floorboard back there...

I have a fuel tank bank there???I can remove that??

This is all confusing. My prop has a 1:1 engraved on it... Back to my exhaust. I installed it last night and WOW what a hard job for me and not the right tools to cut it. When I took old hose off I noticed that one muffler had been cracked and epoxy repaired at the male end. Now I cannot fit the new hose (wire reenforced) as well on there as the soft was. Since I cut hose the size of soft it made for a tight fit. The pressure from riser to muffler seems so tight it would have no way of poping off.. True??? And how do you reach the clamps at the very back of boat??

If original, the motor should be a reverse rotation 351w with a 1:1 tranny. The 1.23:1 transmission that reversed the direction of the motor (allowing a standard rotation motor to be used and still turn a RH prop) was introduced in 1989. There are 1:1 boats with RR motors as new as 1994 though- the 1.23 was an option (though most boats had it).

In case anyone's curious, theres a 1:1 '93 on ebay right now. '93 1:1

If it was hot then you dumped cold water into the engine then that's different.

True for corrugated bendable exhaust hose, not true for smooth exhaust hose not intended to be bent. I got away from the corrugated exhaust hose on my '77 Martinique by using these mufflers. the straight and smooth exhaust hose I used did not have wire reinforcing. The angled mufflers created a straight shot from the riser outlet to the muffler once the muffler was moved forward a bit. This required the hose between the muffler and thru hull to be lengthened as well.

This is going to sound so dumb...So the deciding factor of a reverse rotation is the prop and not if it is going the same as say my chevy subarben. What a dork am I??? I get it I think. The prop spins reverse the motor spin???
A whole new area for me to learn..If I new how to post a pic I would. It is a 351 commander 1985, 2001 nautique...

Thank you I was a bit worried... Nope Let cool before trying to start and I noticed that even though the housing was on backwards I could still feel water going into the hoses, obviously just not enough...And that was all before I finally figured out it was not a reverse rotation motor like someone told us.. I woke up one morning after two weeks of wondering what it could be and read up on this awesome site and found the RWP test....What a blessing.. Hoping to wakeboard on our new nautique this weekend for the first time....

Wow sinking would not have been good. Tonight I will be installing exhaust by myself. I could only find wire reinforced hose as opposed to what came out of it. The only reason I checked the exhaust is because when I checked the the to see if water was coming out of exhaust while running and only one side was actualling rumbling and the other just had the water coming out but no rumble..(my favorite sound by the way) I got back in boat gave it a little gas and happened to see the hose breathing and thought that cannot be right...Pulled it and what a mess.!! How would I now if I warpped the heads??? Seems to be running quite well off the hose???

every other

See, you are already well ahead of the curve by being smart enough to check the exhaust hoses due to the overheat. Most people would not think to check the hoses. Do the things you and the others have mentioned, and I bet everything else will be fine.

Sort of says something about running the impellars dry...they can take more of a beating than people realize. Over the years, I have found that age, not abuse, causes most impellar failures.

I hope you didn't warp the heads while melting hoses.

make sure that there isn't any chucks of rubber from the impellor stuck in the manifolds or lines that would cause a water restriction otherwiser your going to melt your new hoses like the old ones are already.
