225 ocean pro nothing but trouble

[jus4funn2010]

I bought a 2002 ocean pro on a 24' CC and had nothing but heartache first time out. would not run over 5100 rpms with a 15x17 prop, then the motor ran very erratic with the rpms constantly fluxuating about 200 rpms even at WOT and then when I started to put in on the trailer the HOT warning came on. Any suggestions?

Have some patience. This ain't a chat room.

OK, I guess you do not want to take it to a reapir workshop? first step is buy a genuine manual, not a CD or a download or a generic manual, but a genuine one, then you need to do some very basic troubleshooting, do not start pulling things to bits, or buying a thousand parts, the scatter gun approach never works, so, remove all the plugs and have a good look at them, do they all look the same? replace them anyway, do a compression check while they are out, can you borrow a complete new remote tank with fuel and hose? if not replace all the filters in the fuel system, while you are doing that, have a look at the fuel in the filters, is it clean, or full of sh!t? is there any water in the fuel? stat with that and see how you go, we need to narrow down the possibilities before any further action.

You bought a 10 year old boat and motor used, and had a problem first time out.

Was the rig checked over by a qualified mechanic before you bought it?

Did you test drive the boat before you bought it?

If the answer is no to both questions, then you should have a qualified mechanic go through the whole boat, motor, and fuel system to do any required repairs and to any maintenance that should be completed, then go out on a shake-down cruise with the mech.

It sounds like this is your first boat.

Taking a new to you outboard and running the snot out of it without first going through it is a good way to kill it. Thats the nature of outboards, its nothing like a car.

I hired a marine mechanic I found on craigslist to guide me through all the maintenance steps before it ever saw the water. Cost me less than $200 and I learned a lot. Then I bought the factory service book and took over.

At a minimum I would rebuild the carbs with new kits.
Replace the water pump and thermo's.
Change the gear oil using new drain seals.
Do a compression test.
Do a spark test by the book, not by looking at sparkplug sparks.
Then test it.

Re: 225 ocean pro nothing but trouble

Ok I guess what I put on here to start with sounded pretty bad so let me back up a little. First Im in my 50's and have had some kind of boat since I was 14 so Ive had MANY boats. Ive never had anything bigger than a 150 and have not owned an OMC motor since 1978. I know that the impellar probably shreaded and is the reason for the overheating issue. I know to look at plugs and compression test. The thing that threw me was the constant surging of the rpms at intermediate and WOT. Ive read alot lately about most motors on the market made in the last 15 years but that does not make me any kind of expert. I just chose this one because it is a local 2 owner boat and I trusted the guy I bought it from. So, no like an idiot, I didnt have anyone survey the boat. I probably should have took the boat on a trial run but I had tried several others similiar and truly expected the engine to be the least of my problems. As it turns out, the guy is an honest man and when I told him about the problems I had, he told me to take it to a good mechanic and have repairs made and he would pay the bill. So, Ill pay the mechanics some extra to "school" me on this boat engine for regular maintenence. Ive changed impellars before, foot lube, plugs, etc. but without a good service manual I wouldnt touch the carbs or anything beyond that. I HAVE killed a 150 merc before and didnt like the bill. Thanks for all your suggestions and Ill let you know what all was wrong with the boat.

That sounds like a good plan.

Now that is a great attitude !

You were also fortunate that the previous owner is taking care of the repairs for you. You lucked out.

Update: Re: 225 ocean pro nothing but trouble

Well after a week at the shop with a REAL mechanic I have all the issues reconciled on my boat. As we all suspected, the water pump impellar was in bad shape and only pumping 50%, probably is why it did good while running but overheat when I was at idle after a hard run. One of the thermostats was stuck so new water pump and thermostats to start. Then we started on the surging and they got same as I got, about 5000 rpms and 38-40 mph tops. New plugs and filters, some fresh gas and still the same. The mechanic took the cowl and plenum off the front of the engine so he could see in the throat of all 6 carbs and the fuel rail to see if anything was obvious. When the sun hit the carbs right, he said he could clearly see a stream of gas going into 5 carbs and nothing in the 6th one. A closer inspection showed that the 5/32 braided gas line between the fuel rail and the carb was kinked and it had sucked the line flat on the carb side of the king allowing very little fuel in that cylinder. Amazing that it didnt scorch that piston. Just be sure an inspection of the cylinder and piston and a good compression test showed it was in great condition. All 6 cylinders had 118-120 lbs of compression... not bad for a 9 year old motor! The mechanic said it was obvious to him from all he looked at that the motor was a very low hours which is what the previous owner told me. I took the boat out for a trial run after the work and it right up to 5800 rpms and with a little trimming hit 6000 and 48 mph. Now Im a happy boy! Took the $875 bill to the previous owner and he offered to pay it all just like he said but I split with him since I would have done some maint. on the boat anyway (plugs filters etc.) and thought we both would be happy that way. It was nice to meet a stand up guy like him that stood behind his word.

Cool. Sounds like you found a good mechanic.

Great story.
Take good care of that engine, it will last a long time.
