View Full Version : 225 Evinrude outboard questions

Have a few things going on with my 225 HP Evinrude outboard. I just burned up my 2nd voltage regulator/rectifier in just a little over a month. Thinking I might have a grounding problem. Also, something is draining down my battery when the boat is not in use. Do you think the two could be related? Another thing is I don't have the power that I used to when trying to plane. If I have a few guys with a good load of fuel, I struggle to get on plane. I don't think it is an internal problem (pistons, rings etc…), so I'm wondering if the engine has some type of power valve that gives it more fuel when under a heavy load. It seems to get to top RPM once on plane and in calm water. There is something not right and I'm at a loss on where to start. Any thoughts?

John do you have a dual battery switch. A friend of mine just hade a problem with batteries going dead and not getting charged when they should be. The switch needed the contacts cleaned. It would not let a full charge go to the battery and not let full voltage go to the electrical sys. so the elec. sys. was always telling the reagulator to give full charge. Thus the alternator was always running at max. output.
And realy I don't know if I fully understand what I just typed.
The lack of power to get on plane, I think you have to many perch on board.

George, that sounds like an excellent start to me. I love the perch overload theory also. I hate to ask this John, but have you peeked in your bilge lately? Slow on plane, battery running down (bilge pump cycling too much?) with a boat that stays in a slip........ I hope I'm barking up the wrong tree.

LMAO George. But the boat has problems even on the way out to fish! I'll definitely check my connections at the battery and switch and clean the connections and any other connections I can get my wrench on. Paul, I really don't think it's a problem with taking on water but I will keep an eye out for that also. What about some type of power valve when under heavy load? It must have something like that in the system I would think.

Well so much for the perch idea.
If it is a feul injected or throttle body fuel sys. it might have control box that would boost the power during throttle up but if it's carburated than the spark should be fully advanced during any throttle up no matter the load in the boat even if you had Paul (ESOX) with you...LOL
Did'nt you have the same type of problem in the spring?

George, it has 6 carbs which is way over my head to try to get them all set properly. In the Spring I had a carb throttle plate come loose and was not opening all the way but that is not the problem this time. I would think even with the spark fully advanced there should be something to dump more fuel in under heavy load.

Way over my head. I dont recall ever seeing anything that resembles an accelerator pump on any outboard, but that sure doesn't mean there isn't one. (Especially when we are discussing an OMC). I'll try to get a hold of my outboard guru tonight and see what he thinks.

With the limited info I could provide, The Guru said what you alluded to, your spark is likely not advancing for acceleration. Take it to a dealer and have them check the ignition module(S).

ESOX, appreciate you checking into this for me. Do you think your guru would want the business or if not, I know someone to call. Thanks again.

Gone Fishing,

What year is your outboard in question?

To rule out the internals (pistons and Rings) you should really run a compression test on each cylinder. One cylinder that is low on compression could cause the problem that you decscribe. Seen it on several old snowmobiles, did not believe it but the compression tester does not lie.

The Ignition would be a good place to check too.

Try giving Lockeman's Marine a call. I am sure they may be able to help. They are not doubt the best Johnson/Evninrude Dealer and Service Center in the area.

Goosewa, it's a 1995 and had a rebuild power head installed 2 years ago. Shortly after that, I ran over a big weed pile that clogged the intakes and my overheat alarm did not sound. It got pretty hot so I pulled the heads to inspect for damage and everything looked good (no scoring of pistons or cylinder walls). Compression test results show some minor differences between cylinders but nothing that stuck out as a problem. I guess I'll start with ignition and spark advance any see if that doesn't correct the problem. Thanks for your input. John

If you need a tow I'm going out teusday morn early. Leaving the ramp at 7:00.
See Ya.

John, I had a problem with mine this spring in the electrical
department. I burned up a coil and my power pack. It was caused by a wire that sat inside of one those little holders that
has the rubber around it. The wire wore through from vibration
in a spot about the size of a pin head which lead to me grounding
out. I don't know if something like this could be your problem
but it is a simple check.

Call the Coast Guard Sta at Shores...ask for the EPO (engineering Petty Officer). Tell him your problem...Those guys do work on their outboards and if I'm not mistaken could use a little extra $$ on their spare time. Alot of them live at Selfridge, close to you...

Just wanted to do a follow up in case it could help anyone else. Turns out that my choke solenoid was bad and flooding out the engine along with a couple carbs that needed some tweaking. Thank goodness, I had this fear of something internal being the problem. I took it to Compass Point Marina in Fair Haven and the mechanic there seems pretty sharp. Also, the owner there walked by my boat and saw the equipment and instrumentation. He had his yard guys pull the boat and store it in the warehouse so that nothing would be stolen. I thought that was a pretty cool thing to do. Thanks again for you input!
