While I had cylinders and pistons on I was not able to turn crank a full rev. After removing cylinders and pistons crank spins freely. I haven't been able to get mag and PTO off to get to crank and inspect. For sure my crankshaft is done?

Thank you all. Have been able to find many answers to questions on this forum. So I Finally got around to taking my starboard 720 apart. Once i got the piston wrist pins out using a pulley I found this. What would cause this? Since I'm going to rebuild would like to resolve any/all issues. Once...

I'm actually past the point in the picture, cylinders are out, carb is out, impeller shaft is out close to removing bottom end out of boat. $$ wise I haven't compared yet. Would I be actually saving $$ if I rebuild as apposed to replace whole engine?

Taking my time on this project, since being on vacation with planned family trips. I know I definitely need to replace all the gaskets and seals, bearings and few others. Would I or should I replace pistons and cylinders as well? They look good to me.

Yes to carbs No to others. I used a wire to gauge how much oil and only measured half an inch from the bottom. How high should the oil level be, up to crack shaft? Never have done this type of job. Question about special tools required for this type of job; mag flywheel holder, mag flywheel...

Update. Pulled cylinders out and piston rods and piston itself doesn't move freely. Still unable to turn crank shaft. Will have to remove engine to investigate further. Question how much oil should be in the crank shaft housing, crank shaft and lower piston rods look very dry?

Yes had plugs removed. Also tried looking on both sides on the pump, but didn't see anything.

First off this forum has been great, been able to find many answer to issues. I have a Sportster LT with twin 720 engines. Last weekend while out in the bay was having issue and found water leaking from welch plug on the tuned pipe on starboard engine. Was able to get back home and flush...

Hello I just purchased a 2002 sportster lt and looking for the shop manual. Would you have a copy or point me in the direction to where I may find one? Thanks.

Thanks for the tip. Will try to see if i can remove the plate in front of it. I did blow air and ran water straight through the line it self and looks fine. just when i do the flush nothing comes out of it. can't seem to find to much info on this boat, 2002 sportster LT (5493). Thinking this is...
