Great picture, I found it! Thank you! Do you know which way turning the stator advances or retards the ignition? I know I have to line up the marks, but I’m just curious.

Hello, I’m trying to figure out what is the proper procedure is for magneto timing on a Rotax 717. I just got a rebuild from SBT and it’s going in a 97 sportster. I cannot find any timing marks on the stator. Also, I was wondering where the pistons need to be, if it needs to be at TDC, or...

Good Afternoon, I’m trying to replace a cracked cylinder jug on a Rotax 717 and was wondering how I check if my engine has been bored out so I can get the right cylinder jug. I checked diameter with some digital calipers and got 82.5 mm. I’m wondering if this is the right way, or if it should...

Hello, I was wondering if anyone knew how to hookup the temperature sensor on the Rotax 717. I bought the sending unit and I know it threads into the top of the engine, but I can’t figure out how to hook it up to the MPEM. I have a small wire that I believe hooks up to it but am not sure how to...

Good Morning, I need a shift cable for my 1997 Sportster and I’m trying to figure out which one I need. I’m finding them on SBT, but it always says “right” or “left”. I know that is for the twin engine sportsters. Mine is the single engine, does anyone know if the twin engine shift cable will...

Good Morning, I have a 1997 Sportster with the 717 engine. I bought the boat about a year ago, and knew it had a cracked water jacket due to not being winterized. I JB welded it as a short term fix and it seems like it is holding just fine. However, I want to fix it for the upcoming season. I...

Thank you for taking the time to include a diagram! I’ll take a look at it.

Good Evening, I have a been working on a 1997 sportster for the past few months and have been recently testing it on the water. The carburetors are rebuilt and I am having problems with surging. I had a day where it ran fantastic (ran it for about an hour cruising around a lake) but the...

Compression was 135/125. The impeller rotates smoothly. I know I’m on the lower side of compression, I’ll have to try and bypass the selector. Also, it wasn’t that the motor was reving, it was actually not responding to throttle. I would go full power, and the engine would rev up, and we would...

Hello, I’ve been working on a 1997 sportster for the past 2 months. I purchased rebuilt carburetors for it off of eBay, installed them and the boat ran great. I was getting poor performance and was pretty sure my wear ring was bad, so I replaced the wear ring and impeller. I tested it today...

Good Afternoon! I am trying to find the right carburetor for my 1997 seadoo sportster. It has the dual Mikuni carburetors and is running the rotax 717. I tried rebuilding the carbs but they were so corroded I ended up stripping screws, so I’d like to just buy a new set of carburetors. I...
