Guys, I guess I need to sell this head because I cannot find domes anywhere.These domes are 36cc, and I want to run 95 octane so I guess I would need 41cc??.. Was going to sell for an ADA racing head, but your thoughts?

For sale, pictures show it is pretty clean. I havent even tried cleaning it so it should come out really nice.. The domes with it are 36cc, one dome has minor scars in it. Will ship USPS priority packed well. . Text 772-333-91three seven with your offer... I also have a Westcoast 44/46mm...

I got this part with a sale, it is an MSD ignition, I bought an XP, 1995 with the 720, he said he had it working with this, I cannot identify it. Anyone know?

I have an issue with my 97 seadoo speedster. The issue is with one of my 717's. Its having issues starting..and when it starts, the rpms are maxing out at about 3.5k to 4k on full throttle. Why?

Hello All, New ski owner here. Bought this ski and went through did basic tune up cleaned fuel filter, changed oil injection filter, changed spark plugs, replaced starter relay. Running full tank of non-ethanol premium and seadoo mix oil. Took the ski out on the lake the other day and after...

One of the engine head bolts on my 717 has sheared off. This is the second bolt in the last three years. Im currently reading compressions of 130 front end and 120 back end. Should i be concerned? Or when I fix this issue will this have an effect on my compression? The bolt and low compression...

Hey guys! I replaced a 717 engine in my speedster and have a question. I know there is a break in oil to run in 10 gallons of gas in addition to the stock injection system. What is the correct oil ratio????? Don't want to get this wrong as I've got a lot of time and $$ in this project...

Hi All, This is my first post and I'm hoping someone might have an answer. I recently purchased (as salvage) a 2004 Seadoo GTI LE. The 717 motor was frozen and my intention was to part it out. After cleaning it up, it looked real nice and I thought I might give a try at replacing the motor...

I need some direction on what to do next on my 1998 GTI. I had it on the lake and it was running as well as it ever had. Heading back to the beach after a 40 min ride at full speed, I made a sharp turn and then idled back to the beach. It stalled before I got to shore and I couldn't restart...

Here's the stage for it all. Lengthy, but I want you to understand. Newly done Premium SBT reman engine (717) on right side. Runs great through all throttle ranges by itself. Older 717 on left side somewhat weaker, but also runs great through all ranges by itself. Carbs have both been...

Hey everyone, My neighbour has a 96 Seadoo GTI that his landlord has been keeping in his backyard and wants to get rid of. The thing is that it hasn't ran in over 4 years, what would it take to get it running? The engine bay looks like it's in good shape and the tubes and wires look like...

I love my Speedster, but this year she is going through some stress. I do not have the manuel which doesn't help. If anyone can help with these problems please do: - stearing wheel doesn't feel tight anymore and barely turns right. However it trys to slowly turn right while driving straight...

Bought a Sea-Doo Challenger with two 717 engines. immediately one of the starters Failed. I removed it and the solenoid was completely rusted so I went and bought another starter and replaced it. I ran it a few times and then put it away for winter. Came back this spring and was going to run it...

Did a top end on my 95 xp. Two strange things. PTO carb will not deliver fuel. Mag carb will. Also, when trying to get pto carb to deliver, engine locks up. Pull plugs, turns over fine, then may lock up again.??? Also did mild rebuild on both carbs. Basically everything expect for needle

Starter gear ring moved out of position and came into contact with magneto housing casting. My son was out on the ski last summer when it occurred (just now getting around to fixing it), and I don't recall asking if it happened while running or perhaps while restarting. By the time I got out...

I have a Sportster 1997 with the 717 engine. My problem is that sometimes (very sometimes...) the engine runs smoothly and well, and I get up at top speed without a problem. After turning off the engine and start it again, it goes up to about 3000-4000 rpm, smokes and runs unevenly. I have...

Hello All, new here. I've become more of an expert at many things by joining forums, so here i go with another one… I recently purchased a 1996 SPI and a 1995 XP. The SPI tested great and seems to be running fine. Unfortunately the XP had (from what i've read) the notorious cracked oil...

Hi, I recently purchased a 1997 GTI and have been having acceleration issues. It has to be a carb problem but I can't seem to figure it out! When I go to take off from idle, giving it full throttle, it kind of plows halfway on plane for 5-10 seconds before taking off. Once it takes off it...

New poster here, I am currently in touch with a seller of a 1996 SPX. Is there anything in general I should be careful of? I will request compression specs and take it for a test drive on the water before buying it. What Psi should I be hoping for? Asking price is $1995 with trailer Ad...
