Congratz on the boat (assuming the engine is OK!)
Even the higher output coils can be a disappointment unless you are routinely running at high revs. You might be better off fitting a solar panel and controller, assuming you can find space for it. A 100W panel will give you 5 amps charging in full sun and 2 or 3 amps on bright but overcast days.
Prices are pretty good for panels at present. I think China have flooded the market and brought down the prices. |

It's a Tohatsu 9.9 fourstroke year 2009.There are screwholes for a starter motor but it is missing.
I am assumng it was electric start, but it has been removed at some time.If it was originally electric start, the presumably it will have a charging coil.There are a load of wires but none leading to the battery,and I will have to do some dismantling to see what these wires do,as they are inaccesible as they are.Was going to do that tonight but my back is killing me having lifted the outboard off and staggered with it on a muddy slope to the car.Tomorrow perhaps.

If the charging coil is fitted there is likely to be 2 or 3 wires not connected lurking, likely to be the same colour, if so chances are they will be 2 or 3 phase ac which would have gone to a regulator/rectumfrier unit (small finned box) to give regulated 12v dc output which is usually connected to the battery connection on the starter, but.....
These things were made in both leccy and pull start variants and have the same engine block so the mounts would be there anyway, most modern motors are one or the other not both so if the cowling has the pull cord opening chances are they fitted a different base under the flywheel without the extras.
Modern leccy start motors tend to come with an emergency pull cord in the tool kit that you have to remove the cowling and top engine cover to manually wrap it around the flywheel to use it.

In the pic below which is a tohatsu 9.8 2009 manual start is shows a charging coil at item 6, it looks to be a 2 phase ac output which would need rectified and regulated to charge from, a motorbike reg/rec would do the job if there's not one already fitted, a 3 phase one would do just leave one of the input phase wires unconnected.
Items 4 & 8 are for the ignition system.
I would imagine the 9.8 is exactly the same motor just slightly detuned for the yank market due to some local licencing laws, I think the 9.9 thing is a great lakes rule where 10hp upwards needs registration.
This one is the leccy components of the leccy start model if it helps.

Taken the engine home and yes it is 4 stroke and has the mounting for a starter but no toothed ring on the flywheel.
Bought a service kit,(impeller, plugs, gaskets,fuel filter,engine and gear oil) cleaned carburettor and on starting it up in ran as rough as a bears bum on a frosty night.Thought it might need a new coil, but on cleaning the electrial contacts it now runs very nicely.
The thing that is now holding the job up is the canopy.Had to replace the windsceen as it was cloudy perspex.Trouble is it was double curved and I have replaced with single curve perspex and the canopy is now a couple of inches short of meeting the windscreen.Will probably have to get a piece of canvas sewn in.Tried lowering the forward canopy hoop, but it still wouldn't meet and I kept clonkng my head on the hoop.
Had project boats before, and swore I wouldn't have another,but I have!! |

I've had a couple of canopies made, not cheap is an understatement!
May be better to mount whole screen further back so it fits if canopy is in good nick.

Have done what you suggest and moved the screen back.The canopy looks to be a home made job, and is fairly knackered, and it hangs like a potatoe sack!Ideally, it needs an ally framed four pane toughened glass windscreen like a Norman 20, and a tailor made canopy.I am going to get it afloat first to decide if it is a keeper, and if so I may invest the thousand or so for a new screen and canopy.
I will have more money in it than I could ever hope to recover when selling it, but that's what happens with boats. |

Thanks for the diagram DF. My engine only has one coil and no starter ring.
The charging coil listed for this engine by Cambridge Outboards is in fact two coils as shown in the diagram.
Will look into fitting charging when
I have sorted the canopy and screen. |
