Great suggestion thanks blackrose I’ll do that. I’m also considering using a underwater go pro to help with the fault finding

Yes Sea dog it’s broke so can’t make it any more broke🤣 and might be good experience for me. I’ll let you know how I go on.

Thanks everyone for this advice. We have owned our 57 foot narrow boat since March this year, it’s a live aboard and we are new to boating. Learning as we go along, so this advice is great, from people who have hands on experience. I’m reluctant to try and fix it in the water, as pearly suggests may be a step too far so we will probably wait till spring when it is out of the water for blacking.

Yes good point I was worried about taking those bolts out. I will try taking the prop of first via the hatch. The propeller is spinning very freely, there is no resistance there. So it’s either the foot or a problem with the propeller. it will be coming out for blacking in the spring so may be a job for then if we can’t solve it in the water.

Thanks for the advice everyone. I will undo the two bolts and take the foot and prop off through the hatch and have look if there is a drive pin or shear pin. I’ll come back with some photos if I’m struggling.

Yes think that’s a good idea, just wondered if it was a quick fix but looking like it could be the foot that’s expensive

Hi Tractor I’ve lifted the motor and I’m left with this, with 2 bolts. I take that the two bolts will hold the leg and the prop. I don’t want to remove the bolts if the leg a prop fall in the tube. The motor turns Ok and the shear pin is fine . The bow thuster is old it’s a Venus 50kgf. I’m not sure wher I would find the drive coupling on my model

Hi we have a Venus bow thuster that has stopped working. we have power to the thuster confirmed with a volt meter. the sound the motor makes is high pitched like it is not engaging with the prop. we have changed the shear pin between the motor and the gear box. we can spin the propeller by hand through the weed hatch but this dose not turn the spindle on the top of the gear box. If we turn the spindle the prop dose not turn. Is the gear box broke? Is there a second shear pin on the prop that we can’t get to in the water. Can anyone help, I don’t know what else I can check ?
