Author Topic:   Before I Buy???

I am looking at Rage 15 with the OMC engine. Yes, I've read pros and cons about Rages. My questions are more toward what to look for when buying ANY used boat.

The boat has not been in the water for 3 years, good or bad? Will certain boat/motor part deteriorate if not used? Example will engine seals dry out and crack because of lack of oil/movement? Can rust develop on the cylinder walls? Can cabs go bad even if engine/gas is winterized properly?

What steps should I take before trying to start an engine that has sat for a while?

A compression test was done in the fall. One cylinder was 10 psi less then the rest of the cylinders. I believe this is within spec, but should it raise a red flag. I do not know each cylinder’s psi, just that one was lower. Should I get the actual readings and what is the low-end acceptable psi

This engine (RAGE OMC in general) seems to go through coil pack very quickly. Is this a job a Saturday mechanic can do? Any suggestions to stop it from happening? I was told it was a heat problem, but not sure if it from the sealed engine compartment, or from lack of water flow.

The keel on this boat is scrapped upped; the bottom paint on the keel is worn away. Looks like lots of beaching. Is this a potential problem? What should I look to diff between normal ware and true damage?

The trailer is a two-bunk trailer without center rollers. I read that Whalers should have center rollers to support the keel. Should this be a concern? If it is, what damage should I look for? In general can/should rollers be added to bunk trailers.

Thanks for the help

Should not be a problem. That OMC engine is a good one. I would have the carbs cleaned and usual tune-up stuff.

Well aa-mar im in the same boat so to speak,i too just bought a 15 rageW/115hp omc and it too has been sitting a couple seasons.First thing before startup im going to pump all the old gas out even though it has been treated with additives and run some premixed gas through it with the vro oil pump,just to make sure it works,after that a fresh set of plugs and ill be on my way.Im also curious about the coil packs,ive heard they are around $120.00 not sure how many there are, but i think i will keep a extra onboard.Im led to believe they are easy to replace.

The power packs can fail from heat radiating off the engine block in some cases. The wires are just plain old plastic insulation (should be teflon) and can melt. The wires also sometimes break where they enter the potted body of the power pack, due to vibration. The packs are unrepairable and not cheap.

The best bet is to inspect them every now and then and assure that the wires aren't flailing around loose and are tied clear of metal surfaces.

When you say the boat has been in the water, do you mean continuously? Is this salt water? How much has it been run?

Sitting idle in the water is pretty bad for a motor. Corrosion problems, as you suspect; also if gas was sitting in the carbs they will likely need rebuilding even if the gas was stabilized.

I'd inspect the hull drains; the tubes may have deteriorated. Not a show stopper, but if they are gone they will need attention.

10 psi off on the compression sounds a bit off to me. How did the plugs look?

Thanks for your comments

Chris, the boat has NOT been in the water for 3 year. I.E. not used!!!

JohnAz I can get the boat for $4000 (as is), I would like it a little less.

The boat is in PA, but the reg is from vermount. I'm not sure where it spent the pass years, but the dealer got it on a trade-in in Sept 2001. He looked it over, did compression test etc and said it ran fine then, but he thinks the power packs will need replacing. He has a very low opion of the powerpack and feels they will go bad just by sitting.

I have replace all the coils at one time or other but they never cost more than $25. The bunk trailer is the recommended trailer.
Tell them boat is crap but you will take it off their hands for 3500 as long as it runs then fix bottom and make pretty sell for 5500 had mine since new and love it. I have almost 400 hrs since new put hour meter on after Third season when it ran lean and I paid thru the nose to fix (check coils first sign of problems).
As long as you want a jet its the best one out their if top end is not an issue.
Mine runs 30mph with 400lbs of passengers would like to here from others about speed and potential to increase.
Post should be associated with Rage in some way. The classic readers tend not to give this odd whaler fair credit.

mjd65 - when you said yours ran lean and killed the top end, do you mean OIL or air/gas mix. On cars, if air/gas mix is not correct (lean being not enough gas) the engine will run hot and eat plugs, values, etc. If it is oil, I would think the whole thing would seeze because of lack of oil.

Who is supporting the powerhead and jet drive parts availability on these old OMC jet engines?
BOB KEMMLER JR posted 03-13-2002 05:00 PM ET (US)     Profile for BOB KEMMLER JR    
Turbojet marine products carries parts for the jetdrive unit and i believe the powerheads are just plain old 115 jhonrude.

BE CAREFUL: I got one a while back at what I thought was a steal. $800 later to my mechanic, It was still a dog. It's a nice little hull, but the engine will clog up and overheat if you look at it the wrong way. There is a reason the prices are so soft afterall. I was lucky to get rid of it quickly, and I might add, I gave the guy a SUPER PRICE. Good luck. Mark

I had the same OMC 115 engine in my 17' jet sled. I was boosted to 130hp, I don't remember how. Also had the Turbo Jet drive. Was a cold hearted bitch to get initially started but then kicked over instantly after it warmed up. Never had a problem with the engine. Got a few pieces of junk in the jet drive but was easy to clean out. Only complaint was the cavitation problem, it is a single stage jet, but the over rev system worked well.

I would buy another jet drive boat but never with only a single stage jet.
