How difficult and expensive is it to rebuild/replace the power and propulsion system for a 15' Rage? I have an opportunity to buy a hull in good shape, but have no clue about what it will take to bring the mechanicals back to life.
Thanks for all advice.

Here is a thread on a ongoing conversion.

If you are thinking of getting a RAGE and replacing the jet drive with another jet drive, I would imagine that project would not be overwhelmingly difficult, although it might be expensive. I don't know where you'd find a replacement jet drive.

With the RAGE, it seems like the jet drive system on some models has not proven to be as durable as the hull. That is not surprising, considering conventional Whalers often outlast two or three outboard engines that power them.

The pointer to the other message thread will give you some ideas about re-powering a RAGE with something other than the OEM jet drive.

At the moment, that project is in progress and the results aren't in, but there is an expectation among some of us that refitting a RAGE with an outboard may turn out to be quite successful. You may want to keep informed on that result.

When the RAGE was in production, it was a strong seller and it literally saved the Boston Whaler company at the time from some very bad buisness losses. There are many of these boats around, but unfortunately most of the boats are in fine shape, it is just their engines that need overhauling.

I'm ASSUMING this is an OMC unit. Their are three powerunits in these boats. According to previous post each boat is different!!! Yamaha, OMC, MERC. Yamaha nice but underpower, OMC better power (not great) but some reliablity problems, MERC fast expensive and not many around.

i've seen the 'OMC JET' unit for $1000 online, new/rebuilt, not sure. As soon as I find the link, I will post it. The only info i have on the powerhead is that it is based, if not exactly, on the jo/ev outboard. rebuilt for $2000-$3000????

A handfull of post on the rage on this board (also check post-classic) some people love them, some people hate them! I don't see how a boat can invoke so much emotion, its just a boat. It has its good points and bad points. Safty good, stearing bad, reliablity questionable. baby the powerunit and make sure the cooling lines do not get clogged (some post talk about a strainer to keep the sand,etc out). Heat seem to be this boats biggest problem, causing powerpacks and cylenders to go bad.

Anyway good luck with it, don't spend to much on it. I've been looking at these boats for a while now, I would not spend more than $1000 for a boat missing both drive and powerhead. A fair price for a WORKING boat seems to be in the $5000 area (i'm on the low side because i'm a buyer!)

The Rage Jet Boat Series did indeed save the whole Boston Whaler Line,as "jihm" states! And it does not get the respect here it truly deservers. A jet boat handles completely different than a outboard or sterndrive boat and most likly is the cause of the love/hate relationship the series has.A different thought process has to be used at the helm,but is easy to learn. The 14' with Yamaha Drive Jet is by far the most easy to maintain and repair at very low cost,for the engine/drive is lifted right out of a Yamaha Waverunner III PWC.A rebuilt 650cc Yamaha engine is $600.00 exchange. The 14' and 15' with the 115 hp OMC jet drive(Johnson/Evinrude V-4 crossflow powerhead)is a orphan,the drive system is no longer being made.A few of the jetdrive parts are not availiable,most 98% are availiable still.The power head is just a run of the mill OMC Crossflow V-4 powerhead,readily repaired and availiable(no mistery to fix or repair).The 15' with the Mercury Jet Drive is the best/most$$$$.The drive is being made and can be upgraded to more a more modern and higher power system by Mercury.The Whole Rage series is affected by the curse of all Whalers-a wet inner foam in the hull.I have a perfect looking 14'in the yard persently that weighs 400 Lbs more than the other 14' i have,with the resultant loss in preformance that having only 50 hp in the hulls. I do not feel or recommend any conversion of a jet to a outboard. The transum/hull as made is just not built strong enough to handle the loads/stress of a outboard-unless the whole transum/rear hull area is completly rebuilt.A very costly conversion when properly done,and the only way enough strenght can be added to the hull to handle the outboard's loads and stress placed in the transum (my personal view). Chose a Rage carefully, maintain the Jet Drive System,and ENJOY!!! the boat for what it can do-that no other drive system offers.

I have read Bob's posts and would consider his approach, if there is not a viable jet alternative. What is the problem with the Rage--is the jet drive system inherently flawed (I find this hard to believe with all of the PWC and jet runabouts available) or is there something wrong with the Rage incarnation of this drive that could be fixed with a 2002 technology jet drive system?

The different jet drives required different mounting areas in the hull.The Mercury does not fit into the area of the OMC,nor does the OMC fit in the Mercury area.The hulls differ in the mounting areas the jets mount to and are built diferent when the hulls are molded-diferent areas are reinforced diferently for the required strenghts and thickness.It's not a matter of which is better,you will have to work with what setup you find on the boat you purchase. The OMC drive never acquired the market share it needed to be profitable,and was dropped by OMC. The Mercury drive when introduced was lesser HP than the OMC units.But it acquired more maket share because the boatts it was used in were smaller and less $$$and sold faster than the Rages.Then Mercury went with more HP to get into the larger more $$$ boats.Now you can get 240 Hp and EFI in the Mercury Line. SeaDoo now uses Mercury Jet Drives,even thought it now ownes OMC-Johnson and Evinrude.There is not any flaws in either of the systems.Operator errors caused alot of the overheating problems-running thur a large amount of weeds would cause low water flow and overheating of the powerheads,operation in very low water would push sand into the powerheads and again overheating.Nothing can be made Idiot proof, directions must be followed or thing will go wrong. Bob's experiment is not finished with the results in,i very firmly believe it will not be positive. The forces introduced from the outboard bracket system are too large for the rear stern area of the Rage as it is built and require a complete rebuilding of the stern area to be correct. Time will tell who is right. Hope this is helpfull.

tuna1 - If I'm looking at a rage (or any whaler), is their a simple 'TEST' for water-log?
tuna1 posted 05-23-2002 03:11 PM ET (US)     Profile for tuna1  Send Email to tuna1     
aa_mar The 2nd Rage that has the water log problem is by far the better looking of the 2 hulls,so just by looking at the hull you can be fooled. At this point the best tool ,i think,is to remove a thur hull on the bottom of the hull at a low point and look and examine the foam for water.It's a problem that is not easy to solve.Every hole(and i mean every hole) that's drilled thur the hull's surface(top,bottom,inside,outside) should be sealed with some sort of bedding compound.Any point water has to get in ,it must be blocked.A would suggest a data base of models weights should be started here for reference.I did not know the 2nd Rage had this problem until a removed it from the trailer it was on and tried to flip it over to remove the old bottom paint,and i could not lift it compared to the first boat.The first boat had bottom damage and very poor repairs when purchased and can be flipped over single handed.Whereas the 2nd hull looks great/all most perfect and can't be moved by a single person. I am trully at a loss as how the water got into the hull?? I am thinking weighting a boat is the only good way to know after a good data base has been established. Don't know what else to report,anyone can be fooled by just the looks.
