I need you to answer two questions to get a better picture

1.Has it got wheelbase?
2. Has it got IFS?

Hahahaha.... saw that one coming.. and the boat has IRS not IFS.

The gear and combination accelerator, they shouldn't be too hard to work out. If its one cable it does the lot, but i'm thinking it'll be two cables, one changes from forward/neutral/reverse, the other controls the fuel. This is because you would most likely have a third smaller side knob that you pull out to activate revs only (in neutral) for warming the engine up or cleaning when you get it home and use the earmuff's connected to the garden hose.

yes it does have a wheelbase when on the trailer and it does have IFS Independant Fishing Seats!

and its got 2 cables one for the gears and the other for thrust! i just need to know wich side of the motor they feed into and how to adjust them!

Well one would only have limited movement for gears, the other would be connected to the throttle (carby or EFI).

As for adjustment, shouldn't be too complicated, they usually have plenty of slack in most systems, i.e. after you change into gear it usually has plenty movement before it start revving..

By the way I dont know a lot about this specific engine, but have done some work on an older outboard so I'm working 95% off common sense and just trying to put my 2 cents in but i could be wrong on some points....

If you already have the control cables you will see at the motor end that one cable in all the way in or out and the other is half way. The half way one will be the gear selector cable. To confirm just move the control box into gear. The first movement will be selecting gear and the other one is throttle. Make sure the forward controls are in neutral. Position the gear cable to fit over the gear selector locator on the engine (it should not have pressure on it, so adjust it to be loose on the peg). The throttle needs to be connected so that it IS firm on the plug (if is a pull to throttle system make sure the throttle is being pushed all the way back to the stopper, if not adjust to suit). If is a push to throttle unit just set it up so that the throttle cable is pulling hard against the stopper. This setup will work fine. I have been a boat motor mechanic for about 10 years now and this has worked out every time. If you have more questions don't hessitate to ask.

ok all done now! thanks for that guys! especialy patrolpaul, your a legend! i did exactly as you said and its now spot on, one last question is do you know what fuel mixture it uses and im a dumbass so youl have to explain it as in how many ml per litre type thing

Post by **patrolpaul** » Thu Mar 16, 2006 4:57 pm

for that model I would imagine it should run 100:1 which means for every 10 litres of unleaded put in 100ml of 2 stroke oil. For 50:1 it would be 5 litres of unleaded to 100ml oil. If you look near the fuel connection it should tell you the ratio. Just check to se if it has an oil bottle on the side of the motor. If it does just fill that up and it will mix/blend it automatically. Just a quick note, DON'T use valvoline it has a rep of gumming up the piston rings. Have fun boating.

Start it off with 50:1 and if it blows alot of smoke reduce it to 100:1

Dude I bought my boat off told me to run the outboard on 50:1 but it blew more smoke than cheech and chong.
Bumped it back to 100:1 and all was sweet.

I've always thought a little more oil to help lube the motor doesn't hurt?

Be carefull 100:1 is too lean on oil in this engine, if you do run 100:1 in the merc stay below 2/3 throttle at all times.

All 2 stroke premix outboards run 50:1 unless it is 45 years old then 25:1 because of shell bearings, even the Yamaha premix models will last longer on 50:1, as with vehicles it can sometimes be smarter to disregard the manufacturers recommendation (100:1 yamaha) it's recommended for reasons other than to minimise wear and gain a longer engine life.

True they can all run 50:1 but if you do a lot of trawling you will gum up the plugs if it is for long durations. You can fix this by giving it some rev's every so often to clean up the plugs. I have worked on Yamaha's for years including high hour professional fishing boats and have not ever had a problem with them due to not enough oil with the oil injection system. I don't know where you have got your facts from, but everyone is alowed to have their own opinion. Safe boating.

maybe i shuold stick to my Patrol! i cant even find where the fuel line ataches onto the motor! theres a square pump lookin thing on the drivers side of the motor with what looks to be three lines coming out of it but ones missing that faces the front, could that be it?

Post by **patrolpaul** » Fri Mar 17, 2006 3:13 pm

If you look closely at the cover you should see directional arrows. If the arrow points in that will be where the fuel line from the tank goes.

Hi Paul no all correct, although I suspect you are talking injected where I was commenting on V840s comments on what I suspect was pre-mix.
Yep non DI, oil injected engines will run around 50:1 at WOT and around 100:1 at idle, as an overall average 70:1 usually suits those that boat for fun, trolling all day will average closer to 90:1 etc.
