Thank you Rob from Black Dog Marine.

Going to fit it over the weekend.
Plan to photograph each section and record all colour codes etc before removal of old loom but any advice on how to approach this task would be greatly appreciated.

Let us know how you get on - been wanting a spin on your RIB ever since I saw it arrive at the club!

We have lots of CIC's planned this summer, i'll get your e-mail from you next time I spot you in the club.

Job done. New alternator and loom fitted.
Wasn't that difficult after all. Spent about an hour preparing taking photos and planning how to remove the old loom and the way the new one should be routed. Last thing off first thing on!!

I changed the belt and filter while I was at it, plugs looked fine so didnt bother with them. Started on the flushing muffs on first turn of the key so Id say that was a good sign, didnt get a chance to put her on the water for a full test yet but hopefully next w/end.

Excellent work, glad you had a successful outcome

So now she's up and running and being good to you, you'll want to be nice to her back so treat her to a couple of oil filters. Air compressors are expensive and known for going bang, oil filters go a long way to preventing that

Where are the oil filters on these motors?

They're little white plastic inline jobbies in compressor oil return lines. Merc say replace every 300 hours or 3 years but at £4 each I do them every service. (couple of times a season)

Is there not another one near the compressor end???
35-8M0042285 FILTER-OIL £9.05
wonder what the service interval is for it??

I saw the inline one when I was at the loom
35-875284T01 FILTER 1 £3.68 , will order today.

Apologies...

The number you quoted is the pair of filters that go in the compressor oil return lines. (The ones I was on about earlier)

The number I quoted is for the filter that goes in the larger diameter oil line that comes from the remote resevoir, filters the oil before it enters the engine.

On the subject of service parts, below is a checklist of part numbers etc I made for my Opti's if it's any use to you. Obviously you may need to change part numbers to suit your motors.

PM me your email if you want it in Word format

Very handy document!!! Especially as it is practically identical to all the service items my engine requires

While on this thread I want to say that the (+)power cable running right through the wiring loom from alternator to solenoid is IMO a bad idea. When the rectifier failed in my alternator the cable melted right through the loom taking most of the other cables with it. (Pic to follow)
I'm Considering running a power cable direct and disconnecting the loom one just to make sure it cant happen again. Any one see a downside to doing this??

Can't think of a reason why not but that doesn't mean there isn't one.

IMO any of the wires in the loom could develop a fault and get hot and melt the rest of them, in my case it was the feed to the injectors.

So you would only be eliminating one of many possible causes.

True, but think there is still more of a chance in the power cable (drawing greater current) in melting through all the cables and destroying the entire loom.

Thanks for that, well handy...

I hadn't got as far as get PN's for the gaskets, the faceplate isn't a service item either but I have had impellors wear grooves on the plate and they can distort.
I always keep them in stock rather than drop the leg, strip down, then wait a week for a parts order

Can you add prices please...

Seriously, top info, thanks....
