Looking at replacing my engine; BMC 1.5. Beta 50 and Canaline 52 are the current favoured options. Boat is Narrowboat 70’ x 7’ and 22 ton. Any feedback would be appreciated. ??

How many of you are using vetus bullflex couplings? What kind of experiences with those? What bullflex model and what kind of engine and propeller shaft setups? How many hours you have used it?

Hello I have a beta 43hp 2800rpm engine and a prm 150 1:2.09 gearbox on my tresfjord 26 boat the propeller shaft is 35mm and 1.8 meters long. Weights aprox 13,59kg propeller is a 17x14 3-blade weight 7.7kg Im now fitting a vetus flexible coupling Bullflex type 8, it weights 11.9kg A smaller Bullflex type 4 that weight 6.9kg would otherwise be good for my aplication but there is no model for a 35mm shaft My consern is that is there too much combined weight on propeller shaft for prm 150 gearbox to handle, will it wear out faster? Is bullflex coupling going to take care of exrta weight By flexing when engaging a gear? shaft, coupling and propeller weight combined is 32.2kg Best regards Henri

Hi. I have a norwegian displacemeant / semi displacemeant Tresfjord 26 boat and im thinking about chancing the propeller. 8m long (waterline is 7.4m) and 2.8m wide, draft is 1m. Boat weights 2500kg fully loaded. Beta engine is rated 43hp @2800rpm, prm 150 gearbox is 1:2,09. It says on beta's website that the right propeller for beta 43 with gearbox ratio of 1:2 is a three blade 18x12. Would a 3 blade 18x13 propeller be over pitched? What kind of propellers do people have with this same engine and gearbox setup and what is the achiavable max engine rpm. I dont want a propeller that is oversized and i wont be able to reach 2800rpm My current propeller is a vetus 3 blade 16x14 and im getting maximum of 3000rpm and at cruising speed my propeller slip is 40% Regards Henri

Hello all. Recently the dual belts on my travelpower broke and after removing them I cruised the half an hour or so home to my mooring. The engine seemed fine without belts on the second alternator with no extra vibration and if anything seemed better due to the lack of the monster travelpower alternator. However. This was a very stupid thing to do. I took the boat out since then and all oil drained out. Well, sprayed out. Everywhere. I refilled with oil and replaced the filter. Tested the engine and still oil droplets. I suspect the leak is between the fly wheel and the engine. This has messed up the standard alternator too I fear as the tacho goes up to tick over but stays there no matter what the revs (checked all wiring). There seems to be a tiiiny bit of play on the flywheel and the gap between the fly wheel and the engine is ominously shiny (approx 4mm). Oil level is stable when the engine is off. How do I remedy this situation?

Hello, On my beta 38 (4cylinder bv1505) there is always a small amount of diesel around the injectors after I've run it for a while. I've cleaned it up with tissue paper, and when I run it again, the diesel returns. It's not a great deal, but enough to make a nasty smell and smokey engine room. I wondered if I needed to put new washers in the injectors? You can't see anything leaking if you look at the injectors (carefully) while the engine's running, but the diesel is certainly there after an hour or two. The engine was run up by a good engineer, so I expect that the injectors are tightened up correctly, but this might not be the case. I'd really appreciate any suggestions! Thanks! Patrick Vale

Hi guys still planning my future narrow beam one of the things i would like is a quiet engine so i was all set on buying the beta marine acoustic engine cover,I know expensive. My boat builder has advised me not to do this as it makes sevicing more ackward and he says with modern day sound proofing materials he can get the same results Any comments from people who have the box or has sound proofed there engine bay.would be welcome, thanks Carl and Samantha
