pull starting

Seen a bit on the forum now about pull starting an engine if the batteries go flat.

Well took the top off mine today and there is nowhere I could pull start the 50hp Hondas.

Is there some sort of extra item that I need to buy and fit so as I could hand pull start them?

Both 12 years old Honda bf 50 hp.

Unscrew the big plastic lid over the top of the flywheel. Health & safety these days would rather you did that in an emergency than loose your fingers the other 100,000 times it starts on the starter......

Lids like that stared appearing in the early 80s - My '78 Yam didn't have one, but the Merc ('82ish) has a partial lid. My old Suz 25 (1993) was fully enclosed.

if you remove the plastic flywheel cover there should be some sort of a pully or groove on top of the flywheel with a cut out or a slot so that a length of rope with a knot on the end can be wrapped around ,perhaps 5/ 6 times ,,put the knot in the slot then wrap the rope around and pull ,,make sure though that the rope will fit into the grove and when it gets to the end of the pull over it will come away from the engine otherwise it could pull you back into engine when it starts,the rope will need a piece of wood to act as a handle on the other end from the knot ,,,,as you live in Durham area where do you launch from normally .

Not sure about your 50, but I'd be surprised if it wasn't the same as my old Honda 40. That came with a pull cord as part of the motor kit. As I recall, it was about 1/4" braided nylon rope, perhaps 3 to 4 feet long, with an overhand knot at one end. The other end had a 4" plastic handle.

Never tried using it, so can't tell you exactly how it works, but the other posters are correct in that you needed to dismantle the the guards to gain access to the flywheel.

Should be in the owners manual, available here:

Rememebr these are relatively big diameter flywheels compared to a Seagull! 5 laps and you'll have enough string to allow you to walk all the way to the bow before it lets go!

Go in short at first, and experiment with longer until you can pull it so it releases from the slot with you still standing on both feet. Start by putting the knot in the slot, and pull it round until you get compression in a cylinder. Then wind it into the groove from there. - If not you'll waste a lot of the pull moving pistons around with no comopression.

Alternatively check your manaul - a lot of them used to put the Emergency starter cord under the lid, which will obviously be the correct length! Edit - Jyaski can type faster than me!

I've wanted to experiment pull starting my engine but never have always found something better to do. Like watch redtube
Something I'm going to have to try.

And practice manual starting, although not too difficult i question how many people would be physically capable of pull starting an engine if the need ever arose?......And make sure you have the correct tools to remove the cover kept on the boat - i know someone that had the pull cord but not a spanner to remove the bolts and had to be towed in by a trawler.

and as i mentioned in another pullstart thread a few weeks ago ,,if you are always used to electric starting make sure there is no one right behind you when ,you pull it over ,,, you dont want to elbow and give the wife a black eye and knock out her front teeth ,,and check it wont start up in gear,, last thing you want is to fall back on your arse or have a man overboard situation if it does take off suddenly or you over balance , and as GIBBO50 just said make sure you can remove the bolts holding the cover and they are not rusted up ,,,,,ere 9d280 how do you know i am used to a seagull ,,lol
