The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Got all injectors out of both engines and sent them out for cleaning. 10 came back with all the numbers the same before the cleaning and two came back "dead". I am beggining to think that I just wasted $170.
My question is that there are two gaskets sandwiched at the head (spray nozzle)...
Twin 2001 150 HPDI's - Port motor starts to loose RPM's (2000+ drop) when it hits 5000 RPM. Used the YDS software and got the code for injector. Cleared the code, duplicated the problem, and then no more code. I have narrowed it down to an injector because I switched out the VST tanks and...
The problem started when one of my throttle bodies froze up. I pushed the throttle so hard that I thought I stretched the cable because the throttles were un-even when I got it freed. I replaced the cables and have lined up the adjustments. The starboard throttle has to be pushed forward farther...

I have twin Yamaha HPDI 150's (2001). On the starboard side of the motor I find this gray wire that comes off of a pigtail and a loose gray wire. They are disconected on both motors. Is this correct, and what do they go to? Thanks
I have twin 150 HPDI's (2001). Here is my guage set-up. 2 Tachs, Speedo (Mainly used for Batt & Fuel level), and Fuel Managment.
The fuel managment guage is the one giving me a problem. The Synch does not work (it used to). The fuel burn is not correct (total and actual). I filled the tank...
I have twin 150 HPDI's (2001 models) The fuel flow gauge is not giving me a correct reading. While trolling it fluctuates from around 3 to 18 GPH, also the fuel burned is off to. I cant find the part # for the little meter that measures the fuel flow. I have separate ones for each motor...
