So so slow to start

[Jim P.]

98 Seadoo sportster 1800. Really wants to take it's time to turn over. once she is running and warmed up I have no problem restarting until next cold start. Any suggestions on techniques with the choke or any fuel additives that might help the situation? I changed plugs. Used Fresh gas. Thanks

What is/ are the motor(s).,,,.Is the battery up to snuff?,,,load tested?
Do the plugs look good?
Can you give us more info?

Rotax 85hp twin engines. I replaced the plugs. Battery recently fully charged but not load tested (I do believe the battery is about 4 yrs old so good thought there). I had the port engine replaced two yrs ago and that starts easier . I had snapped bolts in the exhaust manifold so I picked up a used one on ebay and replaced it. I did notice a bit of a gasket leak with smoke exiting the manifold so I did a shitty job with one of the gaskets.

What battery do you recommend if mine is not up to snuff?

 

[POPPS]

That manifold leak needs to be attended to,,,you will fill the compartment with hot gases, and or spill water into the bilge, a 4 year old water craft battery, most likely on its way out, for sure.

Thanks for the solid advice!

If you put some premix into the plug holes, cold, does it start right up?
