Hello everyone! Great info on this forum but I have some basic questions.

Long story short my nieghbor is selling a 96 speedster twin 717s cheap. Motors look clean. But it needs apolstry. Less than 30 hrs. The boat was not dewinterized and the batteries are dead. I have a red top optoma sitting in the garage and I was wondering if I can hook both positives together on the positive and both negatives together on the negative to use one good battery? Or do I need some sort of isolator?

Also which inlet do I use to run the motors out of the water? The two on top (one is near the oil fill cap) or the two near the bottom bilge?

The neighbor said that it smoked quite a bit at first start out of the water. So I'm assuming that its not getting water in the motor but its a oil/fuel mixing prob. Any ideas?

Hopefully I can get it on the water soon and test her out!

Thanks,

jeff

For the upholstery have a look here, http://seadoosportbo...lstery-t92.html.

If the batteries have been dead for quite sometime, I would probably recommend to just go ahead and replace them. Do you know how old the batteries are?

Let us know how it runs once you get it in the water.

Jeff, by all means do the single battery conversion, a standard 24 size battery will fit in there if you cut the sides off both trays to make one large tray. Just tie the cables together and it will work fine. You can even reuse the original rubber bands around the battery. Some smoke is normal particularly if the unit has been sitting for awhile. That engine has center mounted oil seals which will leak oil into the case as the engine ages. Eventually it will leak too much, but as long as it runs clean after a few minutes you are probably ok. For flushing when hooked up to a water hose use the two top inlets. Leave the two at the rear open. For winterization, i.e. gravity feeding anti freeze into the engine, then you would close off the lower rear locations. Obviously the engine should be running first before flushing with water or gravity feeding anti freeze into the engine. If you don't know the history of the engines or even if you do we suggest a compression test, we like to see 125 to 130 PSI with no more than 5 to 10 PSI difference between cylinders. The result of a compression test is far more important than the number of hours. Good luck with it!
