It's been a while since I've posted here, but that's a testimant to the moderators. My XP150 has been running great since you fellas helped me with servicing the fuel scavenging system. However, I seem to have lost power since then.
First off, here are the particulars regarding the motor and service history:
Model: TE150SLCEM
Serial: R08241230
Boat: 1990 Nitro 185 (18' 10")
Mount: Mechanical Jacking Plate
Prop: 3-Blade, 22 Pitch Raker
Service History:
Sep-2002: New Powerpack
Feb-2005: New coils, plug wires, fuel scavenging valves, fuel recirc hoses.
Feb-2005: Rebuilt carburetors, including flattening float bowls.
Annual: Decarb and replace plugs
Symptoms:
Hole shot has been getting consistantly worse over the past 7 or 8 months. It is to the point now where it's okay when I'm by myself, but if I have a passenger and full livewells and fuel tanks, it won't get up on plane (without the passenger moving towards the bow). In the past, the holeshot was a little sluggish, but I could hear the motor accelerating right up until it got on plane. Now, if the boat's loaded, it will wrap up to approximately 2000-3000 RPM (estimate, tach doesn't work), and stay there until my passenger shifts to the bow helping the boat get over.
Once it's on plane, everything's great. It tops out at about 62 MPH, and runs very smooth. It idles pretty well, although sometimes it dies with a loud spit. On cold startup, it needs a lot of priming, and takes about 20 seconds for it to fire up.
Sorry for the long post, but I'm hoping it will save you all time in having to ask me a bunch of questions. Thanks in advance for what I'm sure will be helpful information!!!![]()
