Oil Injection and carbs
Posted 23 July 2005 - 01:09 AM
This is my first post here. I just got a used Speedster, it was a stolen recovery that I got for a steal (no pun intended) as the insurane had already been paid out. But i had to buy it sight unseen. I haven't started it yet (batteries are shot), but I have a sneaking suspicion that the oil injection may have been disconnected. It looks like it' sall there, but there a re a few things that make me think the previous owner was pre-mixing. Is there an easy way to tell if this is the case? And if so, should I keep misnig or get the injection working again?
Also, the carbs on the STBD side don't seem to move back after opening the butterflies. IS this a common problem? THis is my first jet boat, but I have had a few skis, so I am not a total newbie (although it may sound that way!)

He is absolutely correct. Keeping the 2 lines and the reservoir is so your rotary valve drive gear and shaft continue getting oil. Some people prefer to premix, others don't. It may be a good idea on older boats to doo this.
I just got my 96 speedster last year. This year I lost oil injection in one cylinder. Im in the process of fix my cylinder wall. I spoke with a mech on going to an oil mix in the gas. He said that I need to keep the oil reserve and two lines coming and going from both engines. I will know more when I get in to it. But It is supposed to do with the main crank of the engine and keeping an oil sump in there or something. I'll keep you posted.
