I’ve got a 1999 Sea-Doo Speedster with twin Rotax 787 engines, and one thing I’ve learned from owning it is that slow cranking isn’t always caused by a bad earth or loose electrical connections.
It’s interesting when you search online for information about slow-starting Sea-Doo engines. Most of the advice focuses on checking battery connections, earth cables and wiring.
While these are definitely worth checking first, after owning this Sea-Doo and having to replace a starter motor previously, I’ve realised that sometimes the starter motor itself is the culprit.
Rather than replacing it again, I decided to recondition the existing starter motor.
I disassembled it, cleaned up the commutator and armature, and then reassembled everything.
The result? It cranks like new again!
So, if you’re having slow-cranking issues with your Sea-Doo 787, don’t automatically assume it’s a battery or wiring problem. The starter motor itself could simply need some attention.
Sometimes a good clean and recondition is all it takes to bring it back to life.
