Hello ? I have a 1982 Lund XRF 4.9 Super Pike. The boat is in Mint Condition. It is 17ft long and weighs about 1100 lbs fully loaded. I just bought the boat and have only owned one small 15ft v-bottom prior to this boat with a tiller outboard. I bought the Lund because it was in fantastic shape, has great brand reputation and the guy had receipts for $1,200 worth of work that was recently done to the motor. I even called the shop and they said it was great boat and motor. That work included 3 new carb kits, new plugs, new tilt & trim, complete seal replacement in the lower unit, and a new water pump impeller. Receipt says compression was 120 on all 3 cylinders. The motor is a 1982 Evinrude 75 HP motor. Model # E75TRLCTE. Serial # J0300867.
The problem: I took the boat out today for the first time and the motor started right up & shifted fine. Idles great even after you put it in gear. Thus we were on our way. I opened the motor up and it dug right in and seemed to take off fine. Pushed it to full throttle and once we got up to about 26 mph (reported by the fish finder speed sensor) the boat just seemed to stop accelerating and it sounded like the motor began to bog down. As if it was not getting up to full power. So, 25-26 MPH was my top speed and that was it. I played with the throttle a little bit and when I backed off a little bit the motor seemed to sound better but we didn't go any faster. Unfortunately the tachometer is not functioning but it didn't sound like i was in that optimum 5000-6000 range. I believe the prop is a 17 pitch and it is aluminum. A pretty standard setup based on what I?ve read online. Does this sound right to you? 26MPH? Everything I?ve read online via boaters forums etc leads me to believe that I should get at least 35 -40 mph or so from this setup.
I would don?t have a big budget for motor work but I would like to know if you think there is a problem that can be fixed or if that speed is normal?
Thank you very much in advance for your time.
