We received the new R200 Seasall yesterday to fit onto a Bravo drive, installed in a Pirate 21. First in the UK, if not Europe.

It's a little longer and a little wider than the R170 it's replacing, but not much. Every thing on it is a little more substantial and tougher than the old unit, 10mm manifold studs rather than the old 8mm ones, etc.

Looks like it will be a good exchange for those who want to change to diesel from old V6/V8 petrols, fits Merc and Volvo drives.

That looks very nice.

As someone who put a yanmar on a bravo, learn from my mistakes:

1 for diesels which need more cooling water than the leg can provide, mercruiser provide a blanking kit for the leg and you use a through hull for cooling the engine. Consequently the water isn't flowing through the leg, and that provided an element of cooling to the leg itself.
Take the blanking plug off, feed that to a Y piece and draw water through the leg and the through hull.

2 fit a drive shower.

Fail to keep it cool at your peril

Interesting. Could you replace a KAD44 with a S270? How much do they cost?
 
Interested in this. Having a read up on it now. Is the rev range similar to the petrol V8’s ? Surely not ? Are you having to change ratio on the drive or at least re pitch the prop ?
 
Rated at 3800 rpm. Going from the GM v engines will need a serious think about drive ratio changes I’d think.
 
Be a huge pitch change to drop 1200 rpm in the case and example of a 350 mag v8. Likely at least 6” or more, especially with the drop in power too.
 
Not dismissing it. Just having a think around how it could work. As we know, many have made the mistake of repowering the GM V engines with apparently similar powered diesels, and get caught out by the old ratio issue. Also the different behaving power curve to think about if it was just a prop change. Nice idea, but usually not a wise financial decision over all.
 
I would have thought changing the drive ratio a relatively small cost comparatively. I know on my DP290 the cost would be circa 3k each. The only pricing I could find for the engines was from an Australian site and competitively priced in no way means cheap. Given the price difference I would stick to my own Volvo's should one or both ever go bang.

Bruce, I think that all I could find was the Australian price too which I think was the best part of £30k for an engine and drive combo. I'm guessing that the engine on its own wouldn't be much under £20k so any dreams of this being a sub £5k or even sub £10k replacement would appear to be unrealistic.

Well It's 26k complete with sterndrive right now so maybe a few pennies difference. My point still holds

Yes i agree its still b**** expensive and not worth doing on most boats. Those prices are plus vat and don’t include props which are not cheap.
 
I agree, up to a point. But sometimes I look at my boat and think if it went bang and I was to replace like for like what would I get for 60k ish. The answer is something else just as old and tired and likely to go bang too. If the hull is good repowering to keep is a viable option.

I wonder the same but the KAD series engines are fundamentally good so I wonder if an engine out rebuild with new liners, bearings, etc plus a replacement of ancillary items (turbos, coolers, etc) plus a respray would be a better way of getting another 10-15 years out of the lumps.

These Hyundai's might be shiny new things but who knows what long term reliability and availability of spares would be like. I'm reminded of VW's brief foray into the world of marine engines a few years ago.
 
Of course, Pete. Most times a rebuild is all that is required. But I was thinking more along the lines of a block failure. Thrown rod. Frost damage etc. The crux comes when you have a pair of engines as to when you draw that line if the remaining good is still fine but you know it's over 25 years old (KAD42's)

EDIT

I had a look a couple of moths back what it would cost to put in KAD300's as a straight swap. The only matching pair was in Norway and the price for these second hand engines was in the same league as just repowering with D4's
