Started my engine Sat. morning. A new engine fitted over the winter, now with 11 hours under it's belt. Usual check of the exhaust showed a decreasing flow untill just a trickle. Now I knew I had turned the seacock on so I waited, perhaps 30 seconds, the sound from the exhaust sounded dry so I went down below to check the flow through the clear raw water filter.

Luckily I was bare foot as I would have got very wet shoes!!
The cabin sole was awash with water pouring out from around the steps/engine cover............ Blimey I thought just before stopping the engine. I then removed the engine cover which allowed a large quantity of water to wet the feet again.

I then noticed the end cap of the heat exchanger lying next to the alternator. On examination the phosphur bronze bolt used to attach it to the heat exchanger core had sheared off and the impellor had discharged the water straight out of the end of the heat exchanger.

The broken stud left in the heat exchanger was only finger tight. I had had no cause to touch the bolt during installation. The bolt looks as if it has been fractured from new.

I was extremely lucky this ocurred whilst on my mooring rather than 2 hours later on my way to the Blackwater!

I have contacted the manufacturer, who expressed a hightened degree of concern. They have even sent me 2 free bolts, a spare fuel filter, oil filter and engine anode!!!!!!!

Looks like that may be the end of the matter to them.

I think owners of Beta engines particularly recent installs will be well advised to check these bolts, there is one at each end of the heat exchanger.

Re: BETA BZ 482

THIS IS A KNOWN BETA FAULT!!!!!

It happened to a yacht on the Deben in July and luckilly - Everson's my yard - who fixed this yacht, phoned me to say that this had happened and they wanted to know my engine number in order to send for the replacement bolt kit you got from BETA.

Everson's soberly told me that this was not the first time they had seen this happen, and that is why they took the urgent steps to contact me. It would have been better BETA contacted owners direct (I have recently re-engined) -but luckily I have a very good boatyard, with ears to the ground, that look after Roach!

Re: BETA BZ 482

I am very surprised to hear this tale.

I had a new Beta engine fitted a few years back and I haven't had this problem. It has done about 150 hours or so now.

The only problem I had with the heat exchanger was that the engine anode kind of dissolved inside and when I went to put the new one in, it wouldn't, because the zinc had deposited in the way. So I had to take the heat exchanger apart to clean it out.

This was relatively straightforward, the only problem was putting it all back together again! Eventually got it back, and think I would manage a second time now I know how.

Only other problems I have had is engine cutting out a few seconds after starting due to air in the system. This was easily solved by topping up the diesel in the tank. It's only happened once so far, and I guess this could happen to anyone with any engine?

Also last weekend engine overheated. Stopped engine, sailed onto mooring. Examined raw water filter, no problem. Removed hose and blew down it. No result. Attached foot pump to hose and pumped madly. Finally expelled whatever was blocking raw water intake, and engine was happy again.

I have a 13.5 HP engine. What's yours?

Re: BETA BZ 482

Mine is the 13.5 HP too, I have been told by another forumite that this is a known problem on Beta's engines. So far Betamarine have not deemed it neccessary to contact any of it's customers.
I suppose I was being a bit naive to think re-engineing would give peace of mind. I am wondering if I should have stayed with the bomb proof engineering of the old smokey Volvo MD6A!!

Re: BETA BZ 482

You are right of course, just feeling a bit irritated by spending not an inconsiderable amount of money and being let down so soon.
Up to last weekend I was very happy with it. I am sure love will blossom in due time!

Re: BETA BZ 482

Mine is a 13.5hp. Eversons are going to upgrade the heat exchanger bolts for the new ones in late Sept when she is hauled out. Till then I will have a niggly feeling everytime I use the engine. Apart from that the BETA is a great bit of kit and I am very happy with it, but then again, I have upgraded from a Stuart Turner so who wouldn'nt be?
