1990 Evinrude 225HP worth keeping?

I have twin 225HP Evinrudes on my 30' Scarab Sport that gave me nothing but trouble all last season. I can't afford to buy new engines so I'll probably leave the boat out of the water for the next couple of years until I can save up the cash unless you think they are worth putting more money into.<br />The engines have 776 hours on them. I've had the boat for 6 seasons and the engines have been pretty good up until the 2005 season. I had the boat in 2 years ago (2003 season) to replace a lower motor bracket on the starboard engine and had the mechanic look over both engines and also replace the waterpumps. The port engine had been running rough and hard to start so the mechanic replaced the powerpack, ignition timer base, two coils and repaired the cam roller and pickup linkage. The total repair bill was $3,104.<br /><br />The 2005 season started out great but both engines developed a hard start when cold problem. The starboard engine would refuse to start if you pumped the primer bulb but would start after a few minutes if you didn't pump the bulb. The port engine would take forever to start also but both would run great once you got them above idle speed. During the year they began to stall at idle while in gear (600-800rpm) and started to stall more and more even when not in gear. By the time I nursed them through the season I was fed up trying to get them started and keep them running.<br /><br />I talked to my mechanic and he suggested decarbing the engines and replace the plugs. I did both but it didn't help. The plugs I removed were 3 years old and still looked great (replaced with the factory recommended plugs). When I removed the carb cover on the starboard engine to decarb it I noticed the top carb was pumping gas out of it when the engine was running or when you pumped the bulb, maybe that's why it wouldn't start if you pumped the bulb? I tried removing the big brass screw on the front of the carb and pump the bulb to clear the problem and it seemed to work for a couple of weeks. Then I could tell it was happening again because of the gas rainbow in the water and the engine wouldn't go above 5,000RPM on WOT.<br /><br />When I pulled the boat I did a compression test on both engines, the starboard engine was 108-115 across all cylinders, the port engine was 95-103 across all cylinders. Since the compression test was an after thought the engines were checked cold after I had fogged the them.<br /><br />After this year I feel like both engines have so many problems that I can't trust them. Several times when coming into my dock both engines would stall and I had to be pushed off of other boats to avoid hitting them. The engines smoked so bad on start up towards the end of the year (I use only Evinrude FICHT oil) that people started to complain at the marina. I also wondered if disconnecting the VRO pumps would keep the engines from smoking so much?<br /><br />In your opinion are these problems simple in nature? If I take to my mechanic am I going to be dumping another $3K or more when I would be better off saving the money towards new outboards?<br /><br />Long post but wanted to give you all the information I could. I trust my mechanic but he told me that the engines are probably "getting tired" and it may not be worth the money to put into them. Of course, he also sells new outboards too.<br /><br />Russ

I don't know how mechanically inclined you are, but if the motors were mine I'd disassemble every carb and soak them in carb cleaner then rinse them with aerosol carb cleaner then blow them out with compressed air making darn sure every orifice and passageway was sparkling clean, reassemble them with new carb kits and then I'd test all the recirculation valves and replace any that fail the test.

If I charged $3104 for an ignition job, I would want to be wearing a ski mask. It sounds like those carbs need a rebuild. Get a manual to study, and you can correct that problem.

It really sounds like you need to find a "mechanic" who is KNOWLEDGEABLE with that series of 16 year old motors. <br /><br />Carb rebuilding should be the first thing done, especially since you have a flooding carburetor and poor idle. You may need all new rubber fuel lines, oil lines, etc. due to the engine age. An air leak in the fuel system could also be part of the smoking problem, as could faulty thermostats that don't allow the motors to warm up enough.<br /><br />Read this link over:<br /><br /> http://forums.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=36;t=000028

R. Johnson, I'm not an idiot that paid over $3K for an ignition job. The motor mount aluminum housing was close to $400, I had both water pumps replaced along with lower unit seals in both engines, a new powerpack and coils in one engine. Parts were about $1,200 and the rest was labor. <br /><br />I'm sure I can figure out how to remove the carbs but I'm not sure how hard it is to rebuild them. I will gladly give that a try if it's something that is fairly easy to do. I have the shop book but I don't have a lot of the tools they recommend nor is it easy to figure out where to start when trying to resolve a hard start and poor idle problem.<br /><br />Seahorse, thanks for the link that was interested reading. Everyone I've talked to except for my mechanic (he told me to keep the VRO's) blames the VRO pump for all problems. I replaced the fuel lines and bulbs 2 years ago so I don't think I have an air leak in the system. <br /><br />Thanks for the suggestions so far, I feel a little better that I can resolve the problems and not have to buy new outboards.

Mako224: You did not say what you got for $3104 in your first post, but you did make your mechanic sound like a bandit. It took you two post's to straighten that out. By the way! I'm not an idiot either. Was there a trailering job included in that first bill, or did you forget that too?

Sorry for the confusion and I never implied that you were an idiot. I thought I spelled it out clearly what the mechanic had done in the one paragragh in my original post. I certainly didn't mean to leave anything out, and I trailered the boat to and from so I didn't leave that out.<br /><br />If I would have paid that kind of money to do an ignition job I would have been committed to an institution.

Well first off. I would not get rid of those engines. That is alot of money sitting at the end of your boat, and 'I' would not take the easy (and very expensive) way out and buy new ones. I would replace all the hoses. They arent expensive, and can be done while you are rebuilding the carbs (you have to remove them anyways!) All you really need to rebuild the carbs is pliars, flat blade screw driver, and 2 wrenches! I created a manual on how to do it on a 25hp for a software documentation class. If you would like to take a look at the general procedure, follow this linky... <br /> <br /> How to rebuild 25hp Carb<br /><br />Keep in mind that first off, that is just a first draft, and that it is for a 25hp, yours will be larger, and more of them :)<br /><br />I would def do it myself, save the labor cost, and have some satifaction in doing a job right!

Are you sure it's a fuel problem and not electrical thats cutting off your engines? i had similar problems with my 1995 Johnson 200, and it turnrd out to be an electrical problem. Apparently I had a loose cable on my battery post, that basically caused my Stator to burn it self out. Also one of the magnets under my flywheel broke, so I'm sure that somehow contributed to my Stators early dimise. You may want to check the spark in all the cylinders. Interested in my troubleshooting, check out my link at http://continuouswave.com... my link was listed as: "Johnson 200 Hp stalling under load"..good luck,Jason

Well, we know theres a carb issue from the fact that at least one is flooding over. If one is, the rest probably need attention too. Plus now it's been sitting since last year. <br /><br />And that brings up another issue -- how old is the fuel? Those boats have pretty big tanks. Lets say we use half the fuel. Then the boat sits. Then we top off the tank before the next trip. Fresh gas doesnt mean the old gas is partially new. It means the new gas is partially old. Compound that by a couple of seasons (years) and we may be better off to start over with clean carbs and fresh fuel.<br /><br />BTW -- what are the factory plugs you installed?

I doubt if it is a fuel issue as I use the fuel up pretty quickly and refuel often.<br /><br />Goldfish- Thanks for the link to the carb rebuild info. I'll check it out.<br /><br />Grady- I'm not sure of anything at this point. It doesn't seem like an electrical issue as the engines only cut out when at idle or low speed.
