macscoob

Hi folks,

Has anyone ever had a 9.9 2 stroke yamaha......iv a 16 foot fishing boat its heavy enough as i built it myself. just wondering what these engines are like on the sea....just for some inshore fishing and the like.

Hi macscoob, you should be fine on calm days but for a heavy 16 foot boat I would prefer a 15-20 hp at sea so you can push against strong wind and currents.

I have a 17 foot wooden salmon yawl and its only ever had a 5HP on it. Its been used for over 60 years in the Blackwater estuary and Youghal bay without a problem.

However we do have a very good set of oars on board.

A 9.9HP should be fine, just remember to check the weather forecast in advance.

I'd agree that a 9.9 should be fine, but unsure of your boating knowledge, I'll go a bit further. If your aware already, brilliant. If not, pay attention!

Fergal raises a good point and you can never be certain as to what weather you will run into.
However In that boat, there is no way you should be heading out if there is a likelihood of running into weather where a 9.9 would not make it through. They're fairly powerful, you'd be fine in most situations, if there is reasonable wind and current against you you may not be moving overly quick, but would still make it back in. Just be aware of extra fuel consumption in that sort of scenario.

I'd be more more concerned about ensuring you have the right equipment with you, oars, an anchor, vhf radio, a ladder that can be deployed from within the water so you can get back in if you do fall over board, proper use of the kill cord.
Make sure you tell a reliable person ashore each an every time you go out, when your leaving, your route, when you'll be back and how to contact you, and if your 20-30 minutes late they should contact you, and any issue at all contacting, call for search and rescue. The person shouldn't be annoyed or frustrated about being told and should be willing to make that call, not assume its fine.
The coast guard much prefer to be called and find out your still ok and it was a false alarm than to be searching for days.

If you haven't already, do your National Powerboat Certificate. Even if your experienced you will still pick up some excellent information and tips.

The engine will be fine inshore, on a displacement hull of approx 16 ft or the likes, the hull speed of such vessels being around the 10knots mark,
Though a decent tide can cancel up to five of these....

Cheers for the info lads. i generally only use it on the lakes. i wouldnt go out on the sea if there was any hint of bad weather to be honest, not experienced enough just yet. The fact that its 2 stroke is kinda putting me off. but will have a look.

Why is that? 2 Strokes are lighter, simpler and have less parts to go wrong. The only thing you can mess up is the petrol/oil ratio.

Ye nothing wrong with 2 stroke, for what your doing I'd actually want one.

I have 2 two-strokes; a 3.3 Mercury for the Avon and a 6HP for an 18ft fiberglass sloop (750kgs) The 6 HP is more than adequate for the eighteen footer and I have used the 3HP when stuck. Not fantastic against wind & tide but sufficient. Just make sure you transport it according to makers instructions and use the proper fuel mix (including the correct marine oil in the mix, not stuff for chainsaws or lawnmowers. (because of different operating temperatures, that's why).
