3hp On A 7.5m Boat

[olitay]

Hi Raiders, here is a silly question. I have a 3HP 2 stroke outboard in the shed and was wondering if I could use it as an auxilary on my 7.5 M boat. I know it would be substantially unpowered however as an absolute emergency option do you think it will even move the boat?

The reason i like the idea is cause there is no need for an alternate fuel tank as per the bigger outboards and its sitting there doing nothing so i guess its worth a try?.

Thoughts?

G'day Billy.

I think a 3hp would be seriously under powered as a backup. Any wind or current & you would be going backwards.

I think you would need an absolute minimum of 15 hp to push a boat of that size & even then that would struggle at times.

Sell the 3hp mate!!

Cheers,

Grant.

Thanks guys, didnt think it would push it but it was worth an ask.

Maybe ill flog it and upgrade.

Billy, I'd be selling that motor and buying a 20hp minimum for that sized boat

Hi Billy, I agree with the other guys, but mate since you have it why not try it next time when you are on the water-it would hold you if have another problem like you had a few weeks ago. If it does not push it and I do not think it would either you can then look at upsizig.

Cheers,

Hi Billy,

coupla years ago borrowed my mates 3.6M tinny with a 25HP mariner on the back, also had a 5 HP mariner as an aux.

Drove up the river from oatley to picnic point on a falling tide, took about 25 mins , fished for a while, went to start the 25HP and it wouldnt go.

Thought Oh well ... she'll be right we've got the Aux////

Started first pull and off we went, only problem was the tide had turned, well with a little 3.6m tinny and a 5 HP it took us 2 and a half hours to get back to Oatley!.

Sell the donk, it aint big enough.

Cheers

Chris
