I have a 96 Sundowner 205 with the VPenta 5.0FI (302 Ford Motor). Over the last few weeks I've been experiencing an issue that is testing my patience.
From what I can tell, the boat is dropping into Engine Protection Mode and limiting the RPMs to 2500. Here is what I have noticed when it occurs:
Engine temp reads OK on dash
Fuel pressure reads OK on dash
Engine temp throughout motor reads OK. Read it with IR temp sensor
I've already changed out the fuel filter, completely drained tank to look for blockage and made sure the backflow is not clogged.
What is odd to me is that it seems to always happen on my way home. When I leave the dock, the boat runs great. We will get to where we are going and anchor up for a few hours and then head home. It has happened almost every time over the last few weeks on the way home.
This last weekend I noticed a little surging while the issue was occurring so I'm thinking it needs new plugs and wires but could that be causing the issue?
I'm stumped here.
From other posts I've read, users are saying to disconnect the following sensors to check to see if they are causing the alarm but I'm not sure where each sensor is and most are not listed in the Clymers service manual.
Oil Pressure Sensor
Engine Exhaust Temp Sensor
Engine Temp Sender
Any help you could provide here would be great. It's getting frustrating and I'm sick of taking 90 min to get home when it only takes me 30 min to get to where I'm going...
Thanks Much.
