Outboards (3.3hp 2 stroke)

Hi Folks

Have just got myself a Mercury 3.3hp 2 stroke long shaft outboard which I will keep onboard as a back up when away cruising. Has anyone used this engine in the outboard well, if so how well
did it push the Achilles. Given how easily driven the hull is I would expect in clam water it should move the boat quite nicely. Also
has anyone used the long shaft on a inflatable and does the prop being deeper in the water make any difference.

I used to have a Hurley 22ft long keel with a Honda 5Hp 4 stroke. The Hurley weighs almost twice as much as the Achilles despite being 2 ft shorter and due to this and the long keel had considerably more wetted area. The 5Hp used to reach maximum hull speed of about 5.5 knots easily without full throttle and unless there were big seas never struggled. I would think that the 3.3Hp will push an Achilles happily.

The only experience I have on the inflatable side is that a long shaft 4Hp on a 2.4M inflatable works fine but full power from stationary tends to put the bows back over your head! Fine if you start slowly.

I believe that Chilli Pepper has used a low HP to drive his Achilles and reports no problems.

Yes we have a long shaft merc 3.3 . we ues it on the tender and in Chille .its fine for both jobs. Only prob is when on the tender its never working hard and when transfered to Chille it has to and smokes a lot at first! The other prob is the red horseshoe clip under the stop button ,this can be slightly dislodged then she wont start (ask Aeolus) This only happens when the wind is against you and four on board!!!!
You will not be able to reverse !!! wont swivel in well!
Put extra petrol in one litre cans ,allow to run out then tip the lot in
Make sure mix is exact or the fumes will be bad!!

I have 4hp tohatsu 2 stroke long shaft with saildrive prop, on the transom as backup to my inboard. Pushes the boat along at about 5knots with no trouble. I have no tender so cannot give you any info with regard to use of the engine in this way. I don't think I would fancy moving the engine from the transom to a rib even though the engine is one of the lightest on the market at that power rating.

I pull the dingy along side till engine is just foreward of transom
attach a line to outboard and pushpit release clamps get on board
lift engine on to pushpit with rope( see photo ) and clamp on ,
When I need it I can easiliy lift in to well.Putting the plug into the lazerette is a prob as the bilge pump hose is in the way!
A lot easier than lifting 5 hp johnson from underneath,

Hi Chille Pepper just out of interest what oil mix are you using? The sticker on the cover says 100.1 which seems very weak? 50.1 would seem better to me.

No 100 to one yes it does seem week but ive used it for about 7 years now!
Use the best oil though I think Quicksilver is recomended
It must be marine oil as they do not get so hot as air cooled motors
i did replace the impeller once .(water pump)
I think they are prone to corrosion if not flushed out reg.
I put vinigar in to help kill alkalie.

I have a Evinrude that states 100:1, this is fine and dandy, I tried 50:1 as it seemed weak and the end result is no difference apart from more smoke and it is bound to oil the plug sooner or later.

at the price of 2 stroke oil 100:1 seems a good deal. We are not sure what the mixture should be for our Tomos aircooled engine but am certain it won't be that good nearer 50 : 1, but still only used by Linda to wizzzzzz around the marina in the Tender most of the time .
