Horse power

[wayneybago]

Hi first question I have is does anyone know what HP the HT6354 Perkins diesel engines have,.

Then the second question I have is will these be powerful enough to be on the 52 foot Bruce Roberts steel waverunner?

Thanks for your help.

The HT is a turbocharged horizontal unit that was designed for certain low profile applications. It's essentially a normal 6.354 but laid on it's side.

From memory I think the turbo unit was rated at about 120 HP. I don't know anything about the boat design, but would have thought that if you could swing the right size prop through the appropriate reduction unit then it would be OK if twin setup but marginal if single.

In a boat that size, i would probably go for the standard upright engine rather than the horizontal unit, as critical parts like manifolds etc. will be easier to come by if needed.

Hope this helps

Is that the one in Milford?

 

[Andy Cox]

I see the one at Milford has two standard vertical 6.354's, not the H variant.

Looking at the Perkins data, depending on the configuration, i.e. n/a, turbo, turbo/aftercooled the power range was 120 to 158hp.

The brokers details would suggest the boat at Milford is fitted with two x 220hp. Not sure about that?

I had a 6.354H in my last boat and it was a fabulous engines and so smooth.

Probably half the older boats on our pontoons have a Perkins of some flavour lurking under the floorboards and still giving good service after more than 45 years.Most in Brooms and Moonrakers.Need to be aware of spares and parts availability and decent service history. Most seem to pushing a hull around 35 - 37 feet, fitted to anything bigger will be no rocket ?
One or two respected outfits providing replacement big ticket items such as heat exchangers etc at very affordable prices and probably better quality than OME.ie. Lancing Marine.
Think hard to get bits are for any counter rotating engine. ?

I think most were 145hp with some to 175hp.

Early NA engines were 95hp. Skinny head studs.

First turbo units with the Simms turbo 125hp.

Later Holset tubo engines 145hp, except Navy which were de-rated to 125hp. Charge cooler cylindrical.

GT's came with bigger charge cooler, biscuit tin shape, 175hp.

Contra rotating engines suffer parts shortages for the cam and freshwater pump.

Horizontal engines the parts situation has improved as some parts are manufactured again, such as the riser for the turbo, but I believe there is parts availability problems for the oil scavenge pump.

Its old hat now, very old. I certainly would not be doing the work to put one in a boat now.

Used M185C come up from time to time, I'd be looking out for one of those, if its done more than 10k hours then rebuild with new liners and shells etc. A much better proposition.

Possibly a pair Of M 225 HP. ?
Different kettle of fish with excellent reliability and spares off the shelf.
6 litres.

Depends the HT were either 145 or 175. but excellent engines in their day

 

[burgundyben]

Indeed. they have a lovely sweet spot at 1800rpm.

But, very old hat now.

The Perkins 1006 or Phaser marinised by Sabre as the M130C, M185C, M215C, M225Ti, M265Ti and M300Ti are utterly fabulous in all regards and a huge step fwd from the old 6.354.

Totally agree. I have the M225Ti's in my Trader 445 and I like them.

Yep, 1800 was just right in our last boat. I've always liked the old school Perkins engines. I swear I could get my old H6.354 to start by just looking at the key hard enough. Even when really cold, I never had to use the pre heat 'flame thrower', no throttle and she'd start instantly. A modicum of smoke to start with, as the small amount of oil that had worked down the valve stems burned off and that was it. Loved it.

I now have two M225Ti and agree that they are super reliable - simple mechanical units - very good starters and a good parts supply when needed. They also seem quite good on fuel and being the 225hp variant I feel they are very under stressed.

Those M225Ti are in fact 204hp if you look at the spec sheet. Exactly the same pump test plan as the M215C, just rated for different usage patterns. They'll do 15,000 hours.

I took a pair of T6.354's out of my Huntsman 28 and fitted a pair of M265Ti. Went ok....!

I had seen that somewhere. My feelings are that as we are limited to displacement speed I don't tend to worry about it.
