I tried 30, 40 and 50 gap- can’t say I noticed a difference. Just gonna keep it at 30 to not stress the coil for no reason

Good stuff- looks awesome! I definitely recommend trying to get that pole spring in there- it’s worth the extra effort now- you’ll thank yourself

Cold fusion sells an alignment tool but it’s not totally needed. Install the pump then stick your head in the hull and look into the driveshaft. You can eye ball it and just try to get that shaft to look like a bulls eye in the opening- no rubbing at all. Then take a midshaft and slide it on and...
Sorry to hear- never easy to watch the mind go- especially slowly. My dad has Parkinson’s but it hasn’t effected his mind yet. I see dementia all the time at the hospital and a lot of families like yourself stuck in the “sandwich generation”. My prayers are with your family.

If I could go back and redo mine- I would go with the 3.3 tank- my jazz 4 gallon is alright but I hate having my battery on the bulkhead- if I find a deal on a 3.3 then I would snag that

Everyone runs different trim- so it’s easy to pull off your steering nozzle and then measure from the top of the reduction nozzle to the bottom of the trim ring when it’s at full trim. Same goes for the steering.

100%- visually it doesn’t look like much but the numbers don’t lie. And it wasn’t just up trim- it’s when my steering is turned all the way that also benefited

Here’s a before and after looking down into the pump- might not look like much but before is 80mm and after is 88mm- and the same thing goes for the flow at full turns- the flow isn’t restricted anymore.

It could definitely be just how my setup was- originally I had a full 148 rrp trim system with their reduction nozzle and all- but I can’t remember how their nozzle looks now or how well it’s flowed from reduction nozzle to steering nozzle.
But along the line I ended up with a 155 reduction...
Originally no- however when I set my ski up to ride today I gave myself probably 10-15 degrees of static uptrim. So basically all my riding today was with trim. I liked how it spun with that- but I’ll probably bring the static trim angle down a little since the ski was riding a little too nose...
The snout of the reduction nozzle- in my case with my trim ring, the top portion of reduction nozzle was the biggest killer. I cut the snout off at an angle with more off the top then the bottom. I cut just enough to not make any gaps with my trim ring.

I’ll try to make a long and boring story short- but after riding today and noticing such a drastic change, I had to share my thoughts. This might have been common knowledge to everyone but to me it wasn’t so I’m sure it will help someone.
So I’ve been running an oem 155 pump with an rrp trim...
That’ll be perfect- we dialed ours in perfect with an 11/17 but the reduction nozzle on that one was at 88mm so the 10/16 for you should be spot on!

More compression and more timing if you want the most out of your motor.
I run 93 octane on 32 degrees advance with about 230 psi compression. But that’s just me.... don’t take that was a recommendation.

I mean- wax’s curve is gas friendly.
But if it makes you feel better I’m running something like 32 advance from 1600-4500 and bring it down to 16 around 7000. It’s something around that off the top of my head. But I run that with 93 pump gas.
