fixing my low rpm's
Ok, so about a month ago i posted some things about my ski only tunring 6750 rpms. my prop was very dinged up so i sent it to island racing. havent got it back yet when i get it back, after reading and gaining knowledgeon all the post i think i can go find those lost rpms.i think if i fix these symptoms
- I think i will gain alot back when i put the fixed impeller on
-my plugs might have failed due to a poorly tuned efi
-efi is tuned wrong
when i first installed my free flow, i had it all screwed up, their wer eno leaks but i used a stock tubing and it curved upward to the top of the rear void, then the free flow(the r&d that is just a metal tube with no bend) went streight down to the 90 hull fitting. after i saw some pics of what it should like i have it 45 ing out of the water box then runs level across the hullthen 90's to the hull fitting. It was a catastrophe but no it is nice and clean. with fixing that will i have gained some rpms back? there were never any leaks.
i want to go test it but i have to wait on my impeller

it may have had some crimps in it, but not kinks. i cant get started until i get my impellar. could i be losing all these rpms through those couple things? thanks for all your help in advanced.

so just looking through my jetksi tring to find some more causes, my jetworks valve is the regular one where you insert the washers, when i take it apart there is only a spring and a washer in it, should there be something more? would this cause a loss?
im going to post some pictures of the color of my plugs, im not sure what color they should be, im red/green color blind. so its kidna hard to tell what color it should be.
