if that's the case ... gonna go turn the hose back on.:thumbsup:
WOOOOO HOOOOOOO, finally made it to the lake. perfect day. weather was pushing 90 and the water was like glass at a brisk 63 degrees.
this watercraft has never performed this well for me. it is snappy like it should have been a long time ago. before the new motor i was always chasing some little problem. broken water regulator spring, grey fuel lines, gunked up raves valves, .... just about the time i thought i had it worked out the motor went. i used to have to "pump the throttle" to get it to catch and pop up while getting squirrelly. now it just goes. no stall, no delay, it's just up and out of the water. it's almost like a "brand new machine". lol
i have put 2 hours on it so far. my arms get tired the first few times out. i tried to run it at varying RPM's. never exceeding 6000. only burned half a tank of fuel so i still have a ways to go before it's "broken in". i have a few things of concern that i'll go over briefly.
thanks again to everyone who has helped me. sorry it took so long. we had a really "off" year weather wise.
things that concern me, ...
i have to pump the throttle to get it to start. -
it seems as if the carbs aren't holding fuel pressure. once it does fire up it lags until fuel gets to it fully. i can hold it at full throttle and it sputters and starts after cranking over a couple times. then while continuing to hold it wide open the RPM's slowly increase until it fully loads up. takes a few second. 5 -10 maybe. it's idling at 1540 and does fine once it goes. i can cruise around at idle speed with no problems. once i do give it gas is it very responsive and seems to be fine. no cutting out or sputtering at any speed.
the ignition housing and crankcase are getting pretty warm -
after running for 15 - 20 mins the ignition housing and the crankcase, near the rear of the motor, feel warm. i can hold my hand on them, but if they were any warmer i wouldn't be able to. the top end, as well as all of the exhaust is cold to the touch. pretty much "lake temperature". my pee hole is peeing. when i squeeze the oil bath line on the IN side it moves in the tube on the OUT side so i know my oil bath is good. this may all be normal, just need verification that it's ok to be warm.
vibration at 3500 - 4200 RPMs -
i'm gretting a slight grumbly vibration that starts at around 3500 RPMs. it stops once i get up to 4200, or so. the motor responds smoothly when throttled, but continues to vibrate. it gets a little rhythm going if held at around 3800. i have replaced my wear ring but i didn't rebuild my jet pump. the o-rings and bearings "seemed" ok so i didn't bother changing them out. it almost feels as if it could be coming from there. but then again it almost feels as if it's coming from the front of the motor. when i aligned my motor, using the SBT alignment tool, it was almost perfect. the alignment tool slid in with just the slightest "bump". you could barely even feel the shaft going into the female end. not sure what the runout is on this. i'm guessing mine was within a few thousandths. guessing ...
i'm going to go over everything with wrenches and make sure it's all stayed tight and solid. if i can work out these few small concerns i think all will be well. looks like it's gonna be a great year. :coolgleam:
