I recently (10-15 hours of running) purchased a '93 trophy with a 150 hp force. Two weekends ago, after about an hour or two of running on and off to fishing holes, the engine lost about 1000 RPM's. As we headed home, we lost another 1000, only able to maintain about 3000 RPM's. The RPM's would jump +/- 400 RPM's too, leading me to believe a possible fuel prob. <br />I checked the fuel, added fuel additive, changed the internal fuel filter, and added a Raycor fuel/water filter.<br />Didn't work again. Same exact problems. So, then i did a compression check: <br />#1 - 47 <br />#2, #3, #4 - 80<br />#5 - 60<br />Obviously there are problems with 1 & 5. I called the local merc dealer, his exact words were "it's toast, but it might make a good anchor." He suggested anything lower than 90 pounds was worthless. <br /><br />Two main questions:<br />1. Does anybody know what a healthy 150 Force compression test would show? <br />2. If there is only 80 pounds pressure on the three "good" cylinders, is that low enough that is doesn't make sense to bother trouble shooting why the other two are lower? <br /><br />Thanks!!
