Re: should i rebuild my force 125

I don't think I would, Sean, but I am not a Force engine fan.

I think I would part it out (Force parts are in demand) on eBay and buy myself a mainstream engine from a major brand, instead of pouring bux into it.

Re: should i rebuild my force 125

I agree with JB that the parts are in demand, but if you don't have the cash for a new motor, they are easy to rebuild yourself as long as you can find the parts. boring will go aprox 75 bucks per cyl. pistons and rings aprox 80+ each Gasket kit 80+/-. I would have loved to buy a new motor when mine went down...gotta be almost 3 yrs ago now, I just didn't have the cash. Tore mine down myself, spent 500 in parts and machine shop ( I had to do only 2 pistons) and, knock on wood, I have had no problems since.

But.......parts are gettting hard to come by, and the electronics aren't cheap if they go next. I, personally, just didn't have the funds for option 2 :)

Re: should i rebuild my force 125

It's a tough decision for sure, I am presently going through the same thing. I decided for the rebuild. Should have the power head together in a day or two. I took a lot of flak, "get a real engine, it's time to move on". Sure a "mainstream" engine as JB put it would be nice. Here's my problem, look around in these forums, the Yamaha's, the Johnson's, the Mercury's. They are not without problems. If you have the bucks to buy a new one, that's a no brain er. A new "mainstream" engine should last for years trouble free right. But if you buy a 9 or 10 year old motor who knows what new problems come with it. Chances are good you will be doing all the little things you just did to the Force and God forbid some thing pricey breaks in a year or two. A long time ago I bought a used boat with A 65 HP Chrysler. On the second day of owning it I removed the spark plugs, one of them was cross threaded. I did not notice the metal shavings that got into the cylinder (dummy). On my next trip it busted a ring and did major damage. I rebuilt that motor myself because I had little choice, my money was in it and it was partially my fault for damaging it. I owned that boat for six years after rebuilding with very little problems and it ran great. So I guess I would do it again. My boat is a good one and I won't mind owning it indefinitely. I put away a little money every chance I get. When the time is right I will go "mainstream", but it will be almost or brand new! The Force gets a lot of bad talk. "It was meant to be an entry level engine, not designed for salt water or real boating". "Move up to a real engine now". I have logged many miles and hours on my Force and have been in all the same places any other boat has been. I have seen many "mainstream" boaters getting towed back in as well. It's up to you and your wallet I guess, but I'm not afraid to go out in my boat just because I have a Force instead of a Yammy.

Re: should i rebuild my force 125

I bought a 1984 force 125 that was used on a (cheap) ski boat with an inexperienced operator. The guy had a buddy that borrowed the boat and he Topped of the fuel tank for his buddy but didn't add oil!! Scored two cylinders so the guy sold me the motor for $50 bucks. I bought the pistons and rings and bought a honing tree all for under $150. I was able to pull the front carbs and rear from the block and do all of the work without taking everything apart. Motor lasted and never failed until 2001 when I finally sold the boat with the motor still running great. Moral of the story is, although the Force's don't have a great reputation, there are success stories. Sometime's the simpler design of the engine makes them very easy to work on as well as maintain. That is the key. I grew up with a vega so routine maintenance were critical to unsuring it would run always. If you don't have the 15K to buy a new Yammy, go ahead and rebuild.

Re: should i rebuild my force 125

sorry ive really been busy lately. i was reading some old threads on rebuilding and one mentioned only replacing the one piston and reboreing just that cylinder but i think that would unbalance the engine unless the new pistons were the same weight as the old ones. does anyone know where the best place to get parts from are(power heads, pistons, rebuild kits etc..). also i priced a new 115 e-tech ($8,500 installed). i have a 125 force and we think it will take $2,000 to rebuild it ourselves. plus any electronics that are bad. that could cost another $1,000. unless i can find a place to get parts cheaper.

Re: should i rebuild my force 125

Sean, I have just finished rebuilding my 1998 Force 120. My friend at Powerhead Exchange did the power head with new pistons, rings, and bearings. I had to buy a used crankshaft also. The main reason I went this route aside from the cost of a new motor is that I already had many new parts on this one. I may have been able to find a sweet deal on a used motor for the 3000 (rebuild and many new parts) I have in this one, but I know whats inside of this one and feel real good about it. This "new" Force cranks up and runs like new! I'm still in the break in period so I'm running twice the oil, cant wait to run it with a normal mix.
