Would love to see. Looks like another motor in my future

Correct . I have a 304 lb Yamaha R6 and everything was down to the gram

I like the C4 . Works well on Dasa motors .

Stock cover weighs 394 Grams

I like the Yamaha line because it is thin walled and it can be bent and twisted like a pretzel and will not kink . Even the cold fusion line will kink if its bent , cutting off fuel dlivery . That and the fact oem will out last your ski . I get it in 3 or 4 foot strips . Retail around $30 but...

OEM Yamaha fuel line . Anything else is a waste of money and time .

Im spinning a 14/19 with long tail cone and 85mm nozzle on 148 setback . With a little old Judge ported 8mm pv

First thing i do with fins in exit nozzles is take cresent wrench and snap them off . After that grind smooth . All they do is cause drag and slow you down . 12 vane mag pump has enough vane surface to straigten out water flow and stop ski from twisting over under power . Only needed on stock...

Stock stator can be rebuilt with new oem charge coil for around 115. That is the part that is often the cause of running problems .

A regular outerwear would be better than frog skin . I put a frog skin on dash of ski and can pour water through it like its not even there . Complete joke that frog skins claims they wont pass water . Try pouring water through an outerwear .

Never mind. Hit the exit nozzle with porting tool.

Maxx pump is solid stainless at liner and outer stator housing .Stator and liner are not pressed in , they are solid stainless . Only part of Maxx pump that is aluminum is center hub bearing carrier . Probably the best salt water pump made . Even oem pumps have pressed in wear ring liners ...

What is everyone useing for exit nozzle on 148 Billet Mag pumps ? Protec nozzle is going to need some grinding to fit over the flange on this pump . Not sure if this pump is supposed to be used with nozzle from some runabout pump , or if skat just got sloppy with machining this thing . OEM...

Nice . I had my ProTec exit nozzle bored to take skat nozzle rings . Any nozzle with enough thickness can be setup that way .

Ive always assembled top ends dry . A lot of breakin happens in the first minute .

Ive got them all here . Had them on scale one day and there is about an 8oz difference down the line , each being 8oz lighter than the next starting with stock lightened to jetinetics aluminum with steel hub , down to rad charging , down to MSD TL being lightest . Ive run them all and am...

Depends on how it is set up . Some race motors only last two hours before a rebuild and would need rebuiling before breakin is over . They are setup with loose clearances and only need a few minutes . There are some articles on Groupk about this . One is the SXI Pro article that takes a...

Kawi Skat pumps all have 145mm stators. Liner can be bored to 142 , 144 , 145. Any good machine shop can do it , or send it to skat. They charge around $200. No need to buy new pump if you have a 140 Skat Kawi
