sportster

I saw the thread with all the graphs of GPH at WOT but what is the GPH at say 30 mph (5500-6000 rpm) ? We usually cruise at 30 so just wondering if anyone has data.

Hello everyone, I just bought my first boat. A 98 sporster 1800 twin 717 I noticed it has the mpem bypass and that tach does not work. Does anyone know if I can wire them up directly to the coil + output? I am sure this has been done before, I dont want to test by trial and error and...

Hi everyone, I'm Stephanie. This is my first time posting and owning a boat. I purchased a 1996 Seadoo Sportster with the 717 motor after being told it only needed a shifter cable. I replaced it myself thanks to SBT. When I put it in the water, it ran like like a champ for about 30 minutes, then...

Just bought a 95 sportster, single 657(don't know the exact size but that sounds close enough) for $100. I have a good 787 in a 97gtx in my shop. Does anyone know if the 787 will fit in the sportster? The gtx hull is destroyed before anyone asks, and I will find out if the 657 is good in the...

Has anyone tried to repair a damaged intake grate? 2005 sportster 155. I sucked up my rope and it broke both arms of grate at rear. It is still bolted in front, but 2 rear pieces are off kilter.

Hi all, I ran into some weeds and had an overheating incident last fall with my boat. This caused some damage to some of the exhaust hoses. Sea-doo does not make the rear exhaust hose anymore so the place I take my boat for service is having problems finding one. I've tried some searches on...

Bought an SBT rebuilt 155 hp rotax 4tec for my 2003 Sportster last year. With less than 20 hours on the engine the number 2 piston disintegrated. Put a scope in the spark plug hole and all we saw was connecting rod with pieces of aluminum in the pan. Any one else having problems with pistons...

Hello all, I am new to this forum and new to the whole boating scene entirely. I just bought me a 2006 Sea Doo Sportster 4-tec. I tried to do all the research I could in order to make a good buy. Tested it out, ran it for more than 30 minutes on the water. The guy admited to the RPM gauge...

Okay so I've been trying to get my boat running and seem to be running into some problems. Unfortunately, I did not follow all the recommended procedures required before not using the boat for 8 months. I live in Florida, so I thought that I didn't have to worry too much about "Winterizing" the...

I was filling up at the local marina over the weekend, they knocked my fuel cap into the harbor (broke the chain). They provided me with a "replacement" that was the right size but wrong threads. I didn't think it was a big deal to get a replacement cap but looks like its expensive because Sea...

Hello everyone, first off, thanks for all the wealth of information that you have all complied on this site. It has helped me tremendously to familiarize myself with my first boat. I am looking to replace the switch for the lights and the switch for the bilge pump. The light switch only goes...

Hey guys, New to the forum. Just bought a 1997 sportster. I got an extra cable along with it that I need help identifying... Is this a reverse cable or a steering cable?

Recently purchased a 2002 Sea Doo Sportster LE jet boat with the 947 Rotax motor and my third time on the lake (after about an hour and a half of riding around) I started to hear a "clanking sound". Videos: Start up sound without water: https://www.youtube.com/watch?v=TztjQobwq1k...

I was boating one day and somehow one of my back seat cushions flew out and I didn't see. Wanting to buy just the back rest if possible but will buy the whole seat if need be. (NOT THE SEAT COVER, THE WHOLE SEAT)

I have a 99 Sportster. One engine gets about 7lbs of pulse pressure, the other engine gets about 3lbs of pulse pressure. Any ideas would be appreciated. Compression is 150 in both motors.

I am looking to replace my impeller on my 2004 Sportster LE DI. I dont want to give up any hole shot, but more speed would be nice. The engine is rebuilt stock. I need advise from a boat guy, all the advise I get is "this works great on my jet ski". Any of you boat guys that have some...

Good day, I have a 2004 Sportster with the 155 4-Tec which my wife and I love. Problem - the guages fuse (located in the engine compartment MPEM fuse cluster) keeps blowing. This knocks out all the guages, beeper, and warning lights. The engine still runs fine. It is somewhat intermittant...
