1976 chrysler outboard

I have a 1976 55hp chrysler outboard Model 559HG I'm trying to fix up. Could someone tell me the head bolt torque and torque sequence? <br />Also, on all the other chryslers I've seen (very few) where the exhaust comes out above the prop, the exit is a small fin moulded into the housing. I have a slot about 6" long, 1" wide that is open, it appears a plate should be bolted on it. I assume the fin is on this plate? Does anyone have a part number so I can replace it, or an old motor they would like to sell the piece off of?<br />Thanks<br />Steve Sutherland

Re: 1976 chrysler outboard

Hello Steve and welcome to Iboats. Cylinder head bolt torque is 270 inch pounds. Does the head have 8 or 10 bolts?

Re: 1976 chrysler outboard

Thanks for responding eurolarva ,I see your from Minnesota too, I live in the SE corner. 270 inch pounds isn't much torque, no wonder mine were loose and had a blow gasket. I have 10 head bolts on mine. <br />As for the exhaust question, the big open slot I have above my prop is 1.75" x 7.5". If nobody has any idea where to look for a replacement, maybe someone would have a picture and I could try to fabricate one. I assume running with the slot open isn't a good idea.<br />Thanks again for the help.<br />Steve

Re: 1976 chrysler outboard

I live in Brooklyn Park. I went to the Jaycees Ice Fishing Contest Saturday and what a trip. Didnt catch nothing but it is cool to see 11000 people fishing on the ice at one time. <br /><br />Here is the torque order. 8 would have been easy to explain however I dont think I can do it with 10 <br /> <br />I am not sure what you are describing on the lower unit. Can you post a picture here or send me a copy and I will post it for you. You got my curiosity going. Email ralgoetz@comcast.net

Re: 1976 chrysler outboard

Thanks for the torque sequence. I've attempted to attach a picture link of my lower unit. What I'm missing is whatever bolts over the slot where the exhaust comes out. Most motors I have seen have a molded fin where the exhaust exits. I'm kind of at a loss as to what gets bolted over it. Any ideas?<br /> <br /><br />Thanks Again for the help!<br />Steve

Re: 1976 chrysler outboard

Hard to tell from the picture. See the one I attached and circled in red. Is this the piece you are looking for?<br /> <br />If so it is called an inlet water plate. Chrysler part number is 40706-1. The part probably dont exist anymore except in junkyards and ebay and in my garage. I have a spare lower unit that I can remove the part from if you need it.

Re: 1976 chrysler outboard

looks to me like he is missing the trim tab

Re: 1976 chrysler outboard

Sorry for the confusing description and picture, I've worked with alot of motors, but this is my first boat motor. Your picture is in the right area, but if your only circling the small bracket behind the fin, I think I'm missing more than that. I edited your picture to show how much I'm missing. Most of the motors I've come across the "fin" (green arrow) is part of the lower unit housing and not removeable. If you had spare parts, I would gladly buy them from you. I was guessing the exhaust from the motor exited through this hollow fin. Is that correct? What does the water inlet do, I know the water intake for my motor is a little further ahead. Jetq36s mentioned a trim tab? What is that? I do have a service manual on order so maybe I can use the right termenology. Sorry for all the questions guys.<br />Thanks<br />Steve

Re: 1976 chrysler outboard

I would not worry about that piece steve. I looked in the part that you have the green arrow pointed to and it is wide open to the inside of the lower unit. That is just where water and exhaust is discharged from the motor. There are probably two small holes on the port side of your lower unit. Water is sucked in through them holes via the water pump circulated through the powerhead then drained via the kingpin back down the motor leg and exit out that big hole. The lower unit I took pics of are probably almost 10 years older then yours. My chrsler is from 67. The 559HG were produced from 1974 to 1976. A trim tab would have been an aftermarket item that is added to the motor to help reduce torque from the motor. The torque will cause steering one direction a lot harder then the other and the trim tab helps to reduce this effect.<br /><br />If your motor is running good you might want to get a parts manual for it. www.chryslercrew.com sells them for about 20 bucks. They also sell factory manuals specific to certian motors.

Re: 1976 chrysler outboard

I got my clymer manual today, The piece is called an exhaust snout. I scanned the picture from the book, but it may be too small to read, I think you can click on the picture to in large it. It looks like it is for the exhaust to exit only as my water shoots out a hole up by the motor shroud. I will start watching ebay, maybe post at the chrysler crew site like you suggested, or try to make one. http://i50.photobucket.com/albums/f341/sbsrkh/ExhaustSnout.jpg <br />Thanks again for all the help eurolarva. Hopfully I can get this thing running before spring.<br /><br />Steve
