X2/900 build

[CA550sx123]

That looks bit.c.hin man.
I just picked up two 900 triple motors with full electronics for $500. Sxi & stx.
Planning an x2 build as well.
Are you planning on using the stock 650 pump, or a 750, or bigger? I just picked up a Solas 12 vane 750 setup for my 750 x2. Would one of those be a better rear-end for the big triple?

Sweet, thats how i got my engines, they were ugly and beat up. i used a stock 650 pump with a big hub swirl cut to fit from impros. and yes the solas pump would be better, i went the cheaper route when it came to my pump and prop

Yeah, I just realized that the 650/750/900 pumps are all 140mm.

question, my stator cooling... is it needed? or can i run it without having a inlet and outlet?

[X2Onthewater]

YES !! That's so clean, I love it.

I didn't get notified that you posted anything ... normally I get an email 🤷*♂️. I'm starting back to my regular job next week and I'm starting on building the manifolds for the V8 Jet SKi project, so I've been really busy.

I can't say for sure, but stator cooling would be much more important if you were running more electronics. It probably wasn't even necessary on the highest draw systems, but I assume they did this because there were running electric trim, gauges, lights, oil level, fuel level and a fairly large battery.

The only thing you will be powering is a bilge pump and charging the battery. The heat created by the stator is directly related to the amount of demand (wattage) so I highly doubt it will be needed. I'm not running mine.

right on, thank you sir

In 98 and up the 900's received the 148mm pumps.
