1989 Force 125 - MPG?

[bluedolphin]

New to the forum. Not sure if this is right place for the question. 1989 Bayliner 2302 with 2 x Force 125's. What kind of gas consumption am I looking at, say WOT, or at 2500 RPM, 3500 RPM, etc.? I hear they are gas hogs. Would I be better of changing them out to Yamahas or Mers, after purchase? I've been reading all the posts about these engines, and I understand they run well if maintained right, but could be a bear to keep running well. Opinions? Thanks.

Use it until they quit, then repower with Honda or Yamaha or Suzuki. You never know how long they will run okay, so use'em up. Gas, ...just bring a good credit card with high limit. Mine best at 3500.....good luck!

Thanks, Robby6950. What is your gas consumption at 3500? By the way, how many gals full tank?

Bluedolphin,<br />I have a 1990 18 ft bayliner bowrider with a 1990 90hp force that is definetly a guzzler. Not sure about the mileage though. It has a 20 gallon tank. I think your boat is a bigger class, probably a bigger tank.<br /> I think I could run at wot maybe 2-3 hours maximum. There should be a sticker on your gas tank that gives you the capacity. Hope that helps!

Bluedolphin:<br />Welcome to iboats you will find a lot of very knowledgeable boaters here. <br />I agree with Robby6950 I would use up the FORCE outboards. Just keep up the regular maintenance on them. But when you repower if you purchase new outboards you are looking at around $20,000 or more for twin 4 strokes if you stay around the same HP. I don’t think I would spend that much money to repower a Bayliner. You figure fuel consumption at gallons per hour (GPH). It will depend on RPM's you will probly do the best at 3/4 throttle but you will need to experiment.<br />Good Luck

Bluedolphin, Welcome to iboats!<br /><br />Excellent choice of boats. The 2302 with twins is a rare find. I have a the same but a '91, and on an average trip, 20 miles to the fishing spot, then a 7 knot troll for about 2 hours, the a 10 mile run to another spot and a 5 knot troll for another 3 hours, then the 15 mile run back to port, I average 1 mpg. I came up with this average by taking total trip odometer(GPS) and divide total gallons used (fill up before I go out, fill up after get in)<br /><br />I would run with the Forces until they don't have anything left. Then think about a repower, many have gone to single 200+ HP, but I would prefer the safety of twins if you go out any distance. Since Force uses proven technology, reliability isn't that big of a problem, theres alot of them out there, and if you know where to look parts aren't that hard to find.<br />Good luck with your new toy if you go ahead with it!

Thanks for all the responses. KnotAddicted, haw many gallons does your tank(s) hold? Kalian, actually, I don't have the boat yet. I'm still considering it. That's why I'm trying to get as many of my concerns answered as I can before deciding to buy this boat. Keep the responses coming, though. Thanks again.

Re: 1989 Force 125 - MPG?

bluedolphin, my tank holds 140 gallons. Everytime I go to the gas station my bank account starts screaming!! Not to mention the oil that you have to add, 6 gallons of gas, 1 pint of oil (50:1). Some years had smaller tanks, between 80 to 110 gallons. If you remove the inspection plate in the motor well you should be able to see the back of the tank, and hopefully the capacity markings.
