Repowering

Hi all...seeking advice on re powering my 1987 mirage 29. The volvo penta 2002 18hp engine I have currently is done. Due to a bad winterization it has a cracked block and a ruined transmission I'm in Ontario and having a hard time finding a suitable used engine to replace this one....I'm not set on any particular brand but I need something! And id like to sail this summer! I have been looking into the beta engines as they are more reasonably priced than the big name brands.. Anyone have experience or input on the beta engines? Or other sources for used engines?

Thanks

Re: Repowering

Beta are good engines, lots of design ideas to make them easier to work on. I would buy one for my boat.

Re: Repowering

Don't repower, replace. With the Internet you'll find a Volvo 18hp sitting on a shelf somewhere.

Re: Repowering

My Volvo MD11 was not worth fixing and I bought a Beta-25 with some upgrades (alternator etc) and am very happy with it.

Some additional things to consider when repowering with a different engine are:
Will you need to rebuild the engine beds for the new (smaller and lighter) engine?

New transmission?

Propeller shaft rotation and possible need for a new propeller.

Getting the correct angle between the engine/transmission and propeller shaft.

Will you need to change your muffler/exhaust.


Once it is all done and paid for you should be very happy. Stanley at Beta Marine (North Carolina) was very helpful.

Finding a great mechanic can save you in the long run; I am still having issues fixed from an installation 2 years ago.

Best wishes,

George

Re: Repowering

The Beta is a good choice. Based on a Kubota industrial diesel, parts are readily available and much cheaper than Volvo.

How did a poor winterization ruin the transmission?

We just repowered with a Beta 38. Keep in mind there is a lot more to the cost of installing a new engine than just the engine. I don't know much about your boat or the Volvo but you may try to find a used replacement first. Beta engines are not cheaper than any of the other big manufacturers either, but they are better engineered for servicing than most.

Know that to repower its gonna cost a lot more than if you found a used replacement that would use the same muffler, exhaust hose, engine panel, wiring harnesses, etc....

.... prop shaft, propellor (if rotation different), installation charges (unless DIY).. it can really add up, perhaps to the point of equalling the value of the boat in some cases..

Still, one needs to be able to power and an outboard is far from ideal...

From what I understand the Volvo 2000 series was not their best line, but finding an engine that matches up as closely as possible to your existing setup (incl gear ratio/rotation) will greatly simplify the job and reduce costs overall.

Re: Repowering

Your between a rock and a hard place

The boat has little or no value without a motor and it not like buying another used boat with and old motor guarantee's you time X of service

If the boat meets your needs and you plan on keeping it for any length of time what else can you do because dropping in another raw water cooled Volvo is not much of a solution as saltwater corrosion is there main failure mode
