Hi. Yes exhaust is well lagged, but of course only the pipe and silencer. Understood about the belts, I'm planning a change to "polly-v" when these are due to be changed.

Hi. This post is about my alternator. Ive been aware of the heat in the engine bay, although not excessively high, as it has vents either side of the hull, it is quite hot and this big alternator can chuck out 150+ A and as a result gets very hot. I'm sure that the cooler it runs the longer it should last. And for a few quid worth doing. The other consideration was that the exhaust is the same side as the alternator and as air is drawn in at the back of the alternator air has to pass the exhaust/calorifier first. I was also aware of the dust from the drive belts, which after 300 hrs running has necessitated in a new air filter. So I have constructed another duct for the engine intake to draw air from close to the other hull vent. Of course, the cooler the air entering the engine the more efficient the engine is. All theory!

Hi. Sorry this seems to have gone into my previous reply? my email is rob (at) robpendleton -dot-co-dot-uk as we are talking addresses and payments can we use email? Hi again. Im so grateful for your help. Just a little confused as to what it looks like as there are 2 different photos in the description, one is a photo the other is a line drawing. If it's the one in the photo (with the round hole) then I think it should be ok. Any idea what diameter the hole is? Although I'm sure I can adapt to my 100mm duct ok. I can get a courier to collect ok? where abouts are you? cheers. Rob.

Hi David. That was another of my Qs but I assume it's down to the fitter (me) to make the necessary "adjustment" to the housing. I have to say that the wiring could be tidier on my unit, so it would be a good opportunity to tidy things up. Thanks for your contribution. Regards Rob

Hi again. The diagonal between studs is 150mm and the pitch between studs is 105mm as near as I can measure. Had another look for model numbers and there's nothing, as far as I can tell it hadn't been painted after the factory cheers Hope this helps.

Thanks so much. It came fitted on the engine from Beta last year, new boat. Raining too much here to delve into the engine bay tonight, but I'll be in there in the morning. I have a 1M length of 100mm dia flexi duct which I intend to terminate close to the vent on the side of the hull, also a large plastic adapter for the alternator end but it wouldn't look too professional. If there was a purpose made adapter, preferably to 100mm round duct it would look better. Thanks

Hi. The only numbers I can see are on the front housing close to the adjusting bolt. I'll attach a couple of photos.

Sounds good, many thanks. I'll take a look later today and get back. Cheers. Rob

Thanks for your speedy reply, I'll bear that in mind.

Hi. We have a Bosch marine 140A alternator on our new boat (beta 43) and wondered if anyone has fitted a cool air duct to the back of the alternator. There are long threaded studs at the back of the alternator which look like they could take an air duct. Any help greatfully received. Rob

Will be in Saul tomorrow am as meeting up with the kids. Need another life jacket so may be in Saul marina.

We had a Beta 28 in 42' Stoke Boat. It came with a 14/9 which was pathetic. Changed it for a 15/10 from Midland Chandlers and the difference was amazing, especially on rivers, but didn't have the chance to try it on serious tidal links but felt much happier and more confident.

Hi Rusty. We too have stopped, in the shade just after Purton. Intend to go to Sharpness and return. We are on NB Chrissie, Blue 60' Trad. Will no doubt pass each other. Regarding the filters, I'd like to change the air regularly and know from past Beta prices the equivalent filter is so much cheaper. Cheers
