Rustic Charm,
Production of the 2003/2003T engines ran from 1983 to 1993, so your 2003T engine was at least 9 years old when it was installed in your boat, and it is now at a minimum, 22 years old.

The 2003T engine was followed by the 40h.p. MD2040 engine which was based on the ISM/Perkins block and used a heat exchanger completely different from the 2000 series engines.

The Canadian version of the Scout 30's all came with the 2003t. From what I can tell most still have the original engine but quite a few have repowered recently. Most have chosen the Beta with only one going with a Yanmar. Because of size constraints most have gone with the Beta 30 which appears to have worked out well. From what I can tell none of the boats have been repowered due to catastrophic failure. Ironically, the only boat with a catastrophic failure of the 2003t rebuilt instead of replacing & that motor had done the great loop prior to shitting the bed so it had a lot of hours on it.

Thanks Doug. I thought the MD2040 used the same heat exchanger.

This was my error, the receipts indicate a 'rebuild'. I keep forgetting it was a rebuild due to the cost. The removal, rebuild and installation costs total just over $15000. It occurred in Cairns half way through a trip from South Australia. And yes, I know, a new engine could have been installed for that amount. It's an itemised account with plastic bag full of receipts, paid in cash. Someone got taken for a ride big time. I wouldn't dare put the 'sellers' name on CF but I'd be steering clear if I'm ever up that way.

Seal kit for 2003T water pump is about $200. It's not the complete repair kit, just the two bearings, two seals, gasket and 'o' ring.

Today I went to Websters and got the two bearings $6 each, two seals $11 each, 40cents for the 'o' ring. My mechanic gave me a spare gasket but he was just going to give me $1.50 worth of gasket paper to make my own until he found he had a spare. So for about $35 I get to overhaul my pump.

Volvo must be making a packet on their parts.

Make sure the springs in the outward and inward rubber seals are stainless. They sell these same sizes as oil seals and the springs rust away in saltwater. You can use the ones from your original if they are in good shape and fit.

Thank you. A timely warning I had not thought of. I havn't put it all together yet, so I'll do that.

Hi Scout 30,
Could you please give me a few more details of what you call 'aluminium & brass oil cooler' ?
I have a 2003T from 1969 with 4000h on the clock and wish to give this 'cooler' a check-up before I head up North on the Norwegian coast later this year.
Thanks and best regards, Niels

Hi Scout 30,
Slip of the pen, sorry !
The engine is of course from 1989.
Best regards, Niels

Hi Niels, the center casings of the oil cooler & heat exchanger are made of what appears to be an aluminum alloy. The ends appear to be bronze & the internal cooling tubes appear to be a brass alloy. There have been multiple failures of the oil cooler due to electrolysis including my own as well as the donor motor I purchased. I'm not aware of the same problem with the heat exchanger but it would also be vulnerable. It's a real pain in the ass to get to the oil cooler but it's worth checking out. Important to note that the oil cooler could look OK but still have significant damage. I'm not sure what the best way to determine if there is electrolysis is but I'd start by tapping on it. I just tried it on mine & you get a dull thud where it's bad & a slight ring where it's good.


I bought an after market cupro-nickel oil cooler with zinc from Lenco for $125 but don't have it installed yet.

[Scout 30]

I'm going to be putting my 2003T back in soon & my mechanic wants to adjust the valves. The motor's got about 1,100 hours on it & it ran great when it was pulled a couple of years ago. Is this a good idea?

[Paul L]

Sure. Not much damage likely you happen while checking the values.

It's not difficult to remove the oil cooler, depending of course if you have the room in your engine bay to get to it.

You need to remove your heat exchanger to get to it. And because you are removing the heat exchanger pull it apart and give it a clean as well.

Both the oil cooler and the heat exchanger commonly corrode away on this model.

I've replaced both with after market ones.

[Scout 30]

I'm hoping that by replacing the oil cooler with one with a zinc the heat exchanger will be protected as well. If you pull the heat exchanger & oil cooler I would recommend replacing all the little washers.
