    Unhappy 94 Polaris SL750 Overheated last year, a few questions

    I had some seaweed plug up the water intake and my 94 Polaris SL750 overheated last year. I was able to clear the debris and the engine started back up and ran, but the heat deformed (collapsed most of the way) the rubber exhaust pipes. Do I have to replace them or is there a way to heat/boil them back to their original shape? If I have to replace them, What is the best option (EBay, web) or can I use some type of flexible hose from an Auto parts store? Also, How likely is it that permanent damage was done to the engine and how can I tell? Thank you in advance for you time!

    Have you inspected the engine? Cylinder compression?

    Not yet. What should it be?

    Using an accurage compression gauge, you would like to see numbers over 120 per cylinder, with less than 5% difference between highest and lowest.

    I. Had the same thing happen to me and 2 of the heads turned dark brown.that's hot.lol. I used a new head gasket, waited till the engine cooled before removong the head. My water rail was a tad warped. 2 gaskets on the water rail exits. Got lucky... no hose burn downs.
    You can go to a marine store and they can match up your hose size. Its uscg approved too.

    Compression test. If good you may have got lucky. If its the molded curvy one then you need a factory one. Post a picture of which one. Sure someone here has a good extra one. Most parts you can find here at better then ebay prices.
