whoops

[gazza2007au]

i purchased a boat last night with a 50hp evinrude 1971 model with electric shifting now it was not pumping water today so i removed the lower unit the impeller was fine but in removing the lower unit i cut the rubber insulation covering the shifting wires to unplug the connectors to remove the gearbox am i in deep trouble now? i just covered the plug with grease and reconnected them

Re: whoops

Probably be OK for a while, but at least you will know where to look if it gives you a problem later.

Re: whoops

i just went and checked the two wires inside the engine cowling where the lower unit wires meet the main wire harness with the blue and green wire pluged in i get very little power my 12v tester pen barely lights up when i unplug the wires and test the harness side of the wires i get very bright light on the tester pen does anybody know where i should look next to find why when the wires are connected properly i get very little power?

Re: whoops

How does it shift when you have it running ?

Re: whoops

The majority of the voltage is being applied to the shift solenoids. Forget the test light scenario....... leave the wires connected and use a volt meter. The volt meter reading should state 12 volts.

Re: whoops

Hmmm. Says you covered wires with grease. I would assume you are not getting a good contact if the LU is not shifting. I also assume you are talking about the wiring under the power head. I would remove the grease and clean knifes up. Goto Home Depot or Lowe's or your favorite building supply store and buy some shrink tubing. Cut a piece long enough to cover the connection. Slip over a wire, make your connection, and shrink the tubing to seal.

Re: whoops

thanks guys i had the motor running not long ago there is power at the knife connections but its not changing gears and the wire i disconnected are on top of the solenoid on the lower unit and also i cant get the motor pumping water i have the lower unit off again for the second time the impeller is like new and i have connected a garden hose to the pipe running up through the mid section into the power head and turned the hose on i get water coming out of the exhaust section but there is no water coming out of the exhaust ports when the motor is running how can i fix this?

Re: whoops

with the lower unit off, I would remove the thermostat and connect a hose to the pick up tube. Turn the hose on and see if water comes out where the thermostat was removed. Chances are, your thermostat may be seized shut or a blockage in the passages.

Re: whoops

i got the last msg after i put the lower unit back on i tested the motor again the motor can run for about 2 minutes with holding my fingers on top of the head before it starts to get hot than i shut the motor down there is no water coming out of the prop and exhaust ports i will remove the head when it stops raining
as for the gears not changing i am still stuck in forward gear the plugs behind the heat shrink on top of the solenoid on the lower unit i replaced both plugs and heat shrunk the plugs the motor is still stuck in forward gear i used the method below to test the knife connectors on the wire harness side in forward/neutral/reverse as below and i got all the correct readings
so now im thinking i should just replace the lower unit all together with another second hand one what do u guys think?


In neutral, you need 12v to the "Green" wire.
In reverse, you need 12v to both wires, the "Green" one and the "Blue" one.
In forward, there should be no voltage to either wire. (The spring loaded shifter dog forces the unit into forward gear)


i tested the OHM of each wire to the solenoid one is reading 0.02 the other one is reading 4.2

Re: whoops

There is a post somewhere in the forum about those solenoids sticking and a process to free them up.

I just saw that ohm reading. The one with the 0.02 reading is shorted to ground. and needs replaced. I would assume you tested from wire to ground on each solenoid. I will place my bets that is the green wire one. The other one is OK. Without the green one (Neutral) you will be stuck in Forward AND I would say that trying reverse will probably engage both gears at the same time and probably cause a very bad self destruct.

Keep in mind also, these are hydro over electric and will not shift out of gear until the motor is cranked. They need hydrolic pressure to move the shift dog.
You should be able to hear the solenoid click without the motor running or be able to feel a thunk in it.

Re: whoops

i cant remember which wire was reading what OHM i can test tomorrow if u like? as for the lower unit i drained the oil and it was milky so i have a seal leaking,bad solenoid and im being told the motor was used 4 times by previous owner (my cousins mate who is a mature man) so the condition is unknown plus the over heating someone mentioned the thermostat i think this would be right so should i repair this lower unit change the thermostat and hopefully have a good motor or just get rid of this motor all together? or should i look for another lower unit keeping in mind the last lower unit i purchased here was $250 for a 15hp johnson so a 50hp may be up around the $400 mark
i do like fixing outboards my last outboard was a 20hp 1973 i repaired all lower unit seals and it ran beautiful

Re: whoops

Bad oil will cause it not to shift. Make sure you used Type-C oil only. BRP calls it Premium Blend Gearcase Oil. Looks like you make have some bad seal in the LU.

A sticking thermostat could be your overheat cause.

Re: whoops

it got the better of me so i went to check with the multimeter the GREEN wire is reading .8 OHM now the BLUE is reading 5.4 OHM i just paid for a evinrude manual online and downloaded it to see how to change the solenoid it seems to be pretty simple but how do the solenoids wire attach to the cover? and im looking at the solenoid cable and cover assy part number 0384459 i looked this part up on ebay minus the first 0 and one came up including the wire,cover,both solenoids for $200 where as crowleys marine is charging $150 for the solenoid cable and cover assy is this the same items?

Re: whoops

I would snag up the one from Ebay. I found the one you were talking about. Part numbers listed match up with yours. Being the lower solenoid is NLA and the upper is $136.63 USD direct from BRP, $200 for all that is a deal. Buy it now!

Check and make sure that you are getting a connection to the solenoid with the green wire. .8ohm still is not a good sign. I would think between 5-7 ohms would show a good coil. Make a good inspection of the wiring and coil before you order it. Could be something simple.

Re: whoops

im waiting for a reply to see how much shipping will be usually its a killer from the US to australia

 

[Aratsman]

Re: whoops

They are not too far from me here in the states. I can't imagine it would be that much. US postal would be no more than $43 USD up to 20 lbs. I can't see it weighing more than that. If it is less than 4 lbs, well it's $13.95. Says delivery in 6-10 business days.

i originally thought it was the forward control box that was the problem i found one on the american ebay for $75 i emailed the seller asking how much shipping will be he quoted $125 i asked why so high considering other sellers with the same item are charging $52 for shipping the seller replied it was only a guess figure that he was willing to charge he admitted he had no clue as exact shipping cost so im crossing all fingers and toes and hopping someone else doesnt buy it before hand

Re: whoops

just an update the ebay seller got back to me and said they can remove the items from the OEM box and send it USPS for $15 i jumped on it with both hands phew!!! glad no one else bought it

 

[Aratsman]

Re: whoops

Good deal. Glad you got it!

Re: whoops

thanks i looked up all the parts on crowleys marine it totaled $501.50 and i scored it for $215 yikkes all though i do have a minor problem it was raining and i was half way thought the job i had the lower unit off i was reinstalling the water pump when i left off the spacer that joins the water pump to the water tube i over tighten the bolts and didnt relise the bolts came out the bottom of the lower unit it was a mistake and easy repairable should i use JB weld or while i have the lower unit off get these two tiny holes welded up?
