Lund4ver Posted September 4, 2012 Share Posted September 4, 2012 Well I had the boat out over the weekend, and went to start it Saturday morning after getting the boat in the water, and it started right up, but died shortly after that. Did that a few times while waiting for my wife from parking the truck. Took off, boat seemed to run fine once past idle speed, but could only go 10 mph on the lake, due to speed limit (small state park lake). When to return to the truck for the day, and tried to pop the boat up onto plane for a short distance, and it would only muster 3000 rpm, and couldn't get on plane at all.My question is, would the battery be getting bad causing this issue? Bad plugs? Coil? Any ideas would be great. It died once on Leech over the 4th, but ran like a champ that entire weekened....other then when the shift linkage came off, but got that put back and and never had another issue until this past weekend. Thanks in advance for your help. Quote Link to comment Share on other sites More sharing options...

Stopnuts should contact block at idleand WOT. Check TPS set-up. Mustconnect DDT with adapter harness(84-822560A5) to ECM.2.5 Remote control to engineharness connection is poorClean and inspect male and femaleconnectors.ISSUE7. Speed Reduction (RPMreduced or limited to 3000)CAUSE/ACTION7.1 Low battery voltageECM requires 8 volts minimumFuel Pump requires 9 voltsCheck battery and/or alternator.Check electrical connections.7.2 Overheat condition (engineand/or air compressor)Check water pump impeller/coolingsystem.7.3 Oil pump electrical failure Check electrical connection.7.4 TPS failureIf one (1) TPS fails rpm isreduced to 3,000. If both TPSsfail, rpm is reduced to idleCheck electrical connections.TPS sensor seems to be the common denominator between the two. I can email you the maual if you give me your address.
