Auxilliary for 6.5-7m boat

oracle · 07 March 2008, 15:03

I use my boat for diving so carry quite a bit of weight around with me. I've always been fan of twin engines for back up but there really isn't much choice for a replacement boat at the right price (cheap) with twins on.

Does anybody have any experience/ recommendation of what can be achieved with a reasonably sized aux. on a fairly loaded 6.5m-7m? I can't help but feel an aux. really is going to struggle with that sort of boat.

Lots of threads on the subject if you search for Aux or Auxilary

I do have on my boat (halmatic pacific 22 with heavy mermaid diesel inboard) an auxilliary Johnson 15 HP engine. That gives the speed for the boat, fully loaded (empty boat is approx 2,5 tones) with 4 persons on board 6-7 kn, on calm water.

That's quite a good speed, that's useful.

Thanks

Serious looking boat too. I love the wheel change with the jack on a rock and the collapsible tubes going into the container!!

Maybe You alreday note one improvement made to my auxiliary engine. I note, that when the engine was in "up" position, it was quite hard for mounting and transom when going on waves. So I put a rope at the leg of the engine and and reeled it through the block mounted above on the A-frame and then to the snatch on the side of the A-frame. That makes riding on the waves with engine "up" stressless and it is much much easier to hoist the engine into "up" position.

Another good idea. One of our earlier smaller boats had the raise/lower Aux bracket and it REALLY took some lifting and was none too kind on any fingers left lying around
