657 is difficult to turn over with plugs?
I have a 1995 Seadoo GTX 657 that is difficult to turn over with plugs installed. It turns freely with them out but it is difficult and short with them in. I have the ski hooked up to a car battery as well. Intake isn't clogged either.
I just want some info if any one has this problem, or did

First info is DON'T hook it OR boost it from another source or its going to aggravate you more and more. But pull the starter and bench test it but i bet you need a new one.. $55 on ebay

You can hook it to a car battery or jump box no problem. The problem is if the car/truck is running.
DO NOT HOOK IT TO A RUNNING VEHICLE!!!!!!!!
A car battery is just another 12volt battery, albeit that it has more cranking amps, but still a 12 v battery.
Your starter is weak from the sounds of it...

Weak starter and/or corroded battery cables.

I wanted to assure you guys that I'm not jumping this ski. The old battery was removed and I attached jumper cables to a battery terminals and to a car battery that was not in a vehicle. 12 volts only. Duh!

For anyone servicing a Sea Doo with a external battery out of the hull and (not in any type of vehicle) and connecting it with jumper cables... THIS WILL NOT WORK! The voltage drops to much from the jumper cables for the starter to have enough power to crank the engine under compression. It will only work if the pistons are not under compression, like with the plugs uninstalled. SIMPLY place the battery inside the hull and attach it to the original cables and the ski wont have any voltage drop issues.
I have seen a lot of posts of individuals having this same issue and they try to replace everything such as starter, battery, rebuilding the pump, and rebuild the engine to fix this issue.
I want this to be a life saver for someone in the future. Learn from my mistakes! Haha
