id be happy to help

[@webbracing2021]

Thinking of 3d printing 3 degree wedge to improve cruising on my 760. I know it’s just a family minivan ski but I like messing with stuff? Think it will work ok?

[@EricksonMachinePerformance]

@webbracing2021 100% id recommend making 1.5° first. And you can even make 2 and stack them

What can be done to a Yamaha jet boat

[@fx1mark]

It would be nice if you had a list of services and prices on your website. Do you think removing the bilge siphon tube would make any difference in performance. It seems like it would be a major obstruction to water flow.

[@EricksonMachinePerformance]

I'm getting ready to remake my website it's just having time to dedicate to it. As to the siphon bildge on basically all performance boats I remove them but I've never done a side to side comparison to see if you feel a noticeable difference but I agree with you it is an obstruction in the flow

[@RyanMcIntyre]

I only work on Kawasaki JS boats. The bilge tube isn’t an obstruction to any measurable degree, so I include it even when I bore a nozzle. It’s a passive, discreet, and always on bilge pump.

Beautiful work help me out

[@EricksonMachinePerformance]

How can I help you?

[@carlosdlopezjr1799]

[@JetSkiBuyFixPlaySellChannel]

Call Impros with any impeller questions.

[@shakemum]

[@zixxerlev]

Can you show us a video on performing a cutback and blade thinning on a prop?

[@EricksonMachinePerformance]

[@fabricobblegarage9545]

Is there a difference between boring the nozzle vs a freestyle cone?

[@EricksonMachinePerformance]

Yes

[@rick7916]

Nice can I send you my 2 js550 nozzles? :)

[@EricksonMachinePerformance]

Yes email me [e-mail]

[@coltholder7568]

What other lil mods are there like that?

[@EricksonMachinePerformance]

I'll come up with a list of small cheap mods

[@ivocosta7414]

What benefit you gain by doing this job???

[@EricksonMachinePerformance]

Better bottom end Performance But u loos some top speed.

[@josesantiago8130]

This helps me in the event that a 2017 Rxtx 300 jumps out of the water because the pump cannot process the water due to the speed? It is terrifying when it takes off from the water and jumps, that was a common problem on Yamahas

[@albertosalvatori8666]

1mm...???

[@EricksonMachinePerformance]

It depends on the setup
