Latest project for my 2052 was to improve the engine compartment cooling. I believe the original design is very poor which results in the engine compartment being way above recommended temperature (17 above ambient) when conducting long runs - 30 minutes plus.

I reversed the existing exhaust blower (not needed to expel nasty fumes with a diesel) so it is now sucking cool air and directing toward the turbo intake. I installed another new blower which directs cool air onto the front of the engine. Therefore, the starboard two vents are now a cool intake and the port side are now hot air exhaust.

Obviously, the blowers will only be operated when running forward. When reversing they will be off, which will eliminate any chance of water ingress into the engine.

I'll be doing some runs soon and hopefully will notice a difference in performance.

(may be a little OT)

Are you happy with the 1.7 Diesel otherwise? I noticed Bayliner is now offering it on the 192 Discovery Cuddy (eventual new boat i'm eyeing)-

OT??? Please explain.

Very happy with the performance (for the size of the engine). 'Real' water mileage is about 1NM per litre(metric), fully loaded with a few divers onboard.
I have now done 220 hours since new, in 20 months.

True, she is no speed demon, but for the majority of your boating in our southern waters you can comfortably do 20-23 knots.

I did read a post somewhere, that an owner switched to a 19" s/s high five prop and subsequently could achieve 33knots at WOT(4450rpm). With current 19" 3 blade Aluminium prop I can do 27-28 knots at 4350rpm. I am seriously looking into this...but it is nearly $1000 (aussie $$). Thats alot of fuel (well only 700L).

This engine in a 192 should have very good performance, but could you justify the extra cost? I went for this engine for the economy (aswell as safety), as I do do some big trips (first with the boat was 340nm over 6 nights) and just did another of 300nm a month ago.

(OT= off topic)

"but could you justify the extra cost?"

That's a good question, I figured it could save me about $20us per boating trip in fuel, which would make a lot of boating trips to make up the difference.

Peter,

What brand of blower are you using? I was under the impression that most of the plastic inline blowers are not rated for continuous operation.

The new one is a Rule 4". Other came with the boat. I've asked about continuous ops and retailers beleive it won't be a problem. Time will tell. I'll be runnning the boat around the 10th Nov. for a few hours to test them out.

If they fail, then back to the drawing board. I haven't been able to find a 'top quality' blower over here.

Any recommendations?

Cheers Pete

Pete,

I know that Jabsco make blowers that are 'continuous rated'. However I was curious as to whether the Rule blowers would stand up to extended use, so I fired off an email to the Rule agents. This is the reply I got:

"The Rule 240 blowers are intermittent rated,but we do know from local
experience that they can be run continually for very long periods eg we
have an industrial application in NZ were they may run up to 8 hours a
day and are achieving up 9 to 15 months service.
Let me know details of your application so I can offer more detailed
advice as to whether or not they are suitable ".

Cheers

The "other" reason for a blower is to remove battery gases that may be present...

If you have a fume detector, then you should be good to go... But if not, I'd suggest a blower to suckout all fumes....

BTW, Nice install...

Thanks for that Ken. I ran the blowers for about 30 minutes yesterday running across to an island. There was huge difference in temperature in the engine bay - 'just' warm, on opening the hatch as opposed to 'gees that is hot'. Our crayfishing season starts in 2 weeks, so the boat will be running for over 5 hours per day for 3 days dropping divers all over our local reefs. This will be a good test.

I couldn't pick a difference in performance (didn't think I would). But I'm sure operating in a much lower temperature is better for the longevity of the engine.

I will investigate the Jabscos availability over here....otherwise, we are planning a NZ ski trip :cool: (first time) this winter so I can pick them up then from NZ.:D

Doug - with two blowers sucking cool air in, the same amount of air is being forced out of the other vents, so I'm sure with all the air movement in the engine bay any other nasties will be pushed out, especially Hydrogen gas.

Pete,

Just make sure you throw a couple of fresh crays in the suitcase when you come over!

Ken - depending where you are and where we go, this could happen. I flew 8 crays and a 6kg snapper to Melbourne for a BBQ 2 years ago:cool:

I have also found the Jabsco blowers in Australia too - thanks for the heads up.

We did this about 1 year ago - and love it. I'll get a few more pics in 2 weeks of it being erected and start a new 'completed project'. This will give you a better idea of the construction/versitility.

Note, I have also just installed a full width marlin board too - another completed project and great addition to the Trophy.
