We took our new boat out last weekend. Purchased a 00' Four Winns Horizon with the 5.0 liter over the winter and never checked the motor out till now. Everything seemed good on the run however my oil pressure seems to be high. It's right in the middle of the gauge during idle and pegged at anything over 3500 RPM. I just guessing that it's the sender, but I was looking for opinions from others before I just go switching parts. Everything else worked great, we had it out for a good couple hours. What's your thought?
