I am looking for a back up engine for a 25ft boat, any views on the Tohatsu 9.8hp please. Storage will have to be a consideration, I heard they are not too heavy and could manage to move 25ft er.
 
I'm not really posting this but , I have a 25ft Birchy and need an answer to the same question , and I find the search function impossible , and haven't read the posts because I find the search function , well , impossible
 
So who rattled your cage? /forums/images/graemlins/grin.gif

Yes I was looking at one some years ago, but things change, people have different experiences and using it as a backup is different than on a tender or rag and stick.

I have to choose whether to store it in the engine bay or keep it a permanent fix, difficulties in lifting it, lenght of shaft required or even whether there is now a better product on the market like the new electric motors e.t.c.

I was hoping for these type of replies rather than one from someone who got out the wrong side of their bed /forums/images/graemlins/grin.gif
 
I asked a similar question a while ago about what to replace my aging 4hp ouboard and it seems that the Tohatsu was a very popular choice due to it's power to weight. Have not managed to upgrade yet though.
 
I have just bought a 9.8 Tohatsu.
This is the last year you can get a new two stroke model.
The 6 hp, 8 hp and 9.8 hp weigh in at 27 kg.

My previous 2 stroke 4hp (Marina) weighed 20 kg plus 3 kg of fuel.

I found little difference in moving the 9.8 Tohatsu around and putting it on the tender while at anchor, not tried it yet in a swell and not had it long enough to answer on reliability but very pleased so far.

The long shaft will weigh a bit more but I think you will need it or cavitation may be a problem.

The Zodiac planes well with three of us on board
at 2/3 throttle, with two on board you can not use full throttle.

( Zodiac warn ' 10 hp only for use by a fully loaded experienced operator' /forums/images/graemlins/laugh.gif)
 
I would suggest that Duncan after his comments if moving this size of engine in a swell attach it by a strong rope to his wrist just in case /forums/images/graemlins/laugh.gif

Anyway, interesting and thanks for the info on the end of 2 stroke 9.8 Tohatsu, I saw the 4 stroke but much heavier.

Well if this is the only one perhaps I had bet one quick, I really need my boat and to examine available storage as I would prefer to have it tucked away. I only have a Zodiac 230 so I guess this engine would be illegal on that, that just means I have to store my 3.5 mercury as well /forums/images/graemlins/frown.gif

Thanks,
 
We found 27kg was about the limit of what you could get on and off in a swell. I made up a line with a snap shackle at either end: one end clipped to the outboard, the other to a point on the transom of the main boat. Once the outboard was secured to the tender, the clip was removed from the mother ship, and clipped to the tender's transom. Worst case, the engine would get a dunking, but we could always recover it.

everyone getting into the act? /forums/images/graemlins/laugh.gif

to recap the posts on the use of aux OBs and tender engines etc over the last 18 months -

1. someone quoted 4hp / ton - some agreed and noone disagreed
2. most aux will only be of use in calm conditions
3. 9.8 Tohatsu 2s is a great engine on all fronts
4. sub 30kg generally handleable
5. sub 20kg much easier to handle / stow etc etc (eg the 3.5's)

I would swap my 4hp mariner for a 9.8T tomorrow - just don't have it as a priority purchase. Generally I am happy to tootal around in my tender.
 
Agree with Wiggo. My Yam 8hp is 27kgs, and is really about the limit for getting on / off tender. I also tie a line to it when moving from A to B. Also for when water gets a little choppy, I hook tender onto snap davits and place a piece of board over the bathing platform & side of the tender, unhitch motor, place on board, and slide it back onto mothership hereby providing a level(ish) surface and not damaging the teak. However, there has been one occasion where I didn't even dare do that, and ended up towing the blimmin tender plus motor back to Chi harbour. Still reckon it'll get a dunking one day.
 
I have had one for the last three years.... never let me down. I use it on a 2.6M tender (rated to 6HP I think) goes like stink! I have snap davits holding the tender on which makes putting the engine on a bit easyer in a swell.
 
Mine is on a 2.7m RIB and goes pretty good. Likewise, 3 years old and never let me down. Dinked the prop last season while performing a rapid retreat from the Crown & Anchor at Dell Quay - ie the tide was dropping faster than expected, and was wondering if it may be an excuse to get a different prop. It zooms along at max revs, but just wondered if there might be a bit more.........
 
Thanks for all the replies, seems like this is the one to go for, just need to check shaft length required as a long shaft might not work too well on my Zodiac 230 /forums/images/graemlins/crazy.gif If I could get away with a short shaft I may try it on the tender and see what happens but I think 3kw is the recommended max on the tender.
 
Not sure how helpful this is but I used a longshaft Suzuki 4.5 on a 1.9m slatted floor, the long shaft helped stabilize and stopped the dolphin effect that I got from a short shaft 4, as the slatted floor bows at plane speeds.
You might find the long shaft is more suitable than you would expect but not at wot !
 
Just one more vote in favour of Toh9.8 - use one on a 290 tender, smooth running, easy to start, can be moved (still heavy for one person balancing on an air floor, but the alternatives at same power are worse).
 
Pete, to help transfer my 4hp aux from boat to tender, I bought item 959390 "Practical lifting device for virtually all 2 - 15 HP outboards. Easily fitted, easily removable secure carrying handle with a lock. Straps are resistant to saltwater and UV." from compass24.com

You can use the handle at the top to attach to davit/boat/hand or any other secure point to stop you dropping it overboard.
