2010 Speedster 150 delayed crank after hot?

[Sandow]

I have a speedster 150 2010. After I run the boat for about 15 or 20 min and the motor is hot when I go to start the boat it performs one rotation and then pauses for about 2 seconds and then finishes cranking over. If i open the motor cover and let the motor cool about 30 min it will crank normal again. Talking with a local tech they say there is no issue and i shouldn't be concerned. I have replaced solenoid, starter, battery and checked the charging system. I am running an Interstate deep cycle battery. Is this normal or should I be concerned? Any thoughts on what the issue might be? It certainly is heat related. I have attached a zip file with a video of the start.View attachment SeaDoo Start.zip

Same problem here! Would like to know if you get an answer. The only answer i was told was to get jumper box to carry on the boat. Oh an dI bought my boat in June 2012. Off the showroom floor.

I had the same problem with my 08 RXT last summer. Turned out to be a weak battery. Replaced it and hasn't been an issue since.

Replaced battery same thing. So that's two brand new batteries. With same issue.

Check for corroded battery cables. Clean the battery terminals.

Again this is a brand new boat the terminals and post are shinny and clean with tight connection. the battery is a brand new interstate cranking battery from the dealer. I have looked on other forums and see that this happens a lot and no one can explain why. The only remedy seems to be add a second battery and switch from deep cell to cranking. Also I don't run my radio unless the motor is running. I use power shut off switch when motor not running. I'm gonna try a optima dual crank and deep cycle battery this weekend and see if that helps. I appreciate the responses but it's not battery cable or terminals.
