Update on 1973 135hp that's in the hospital

[paperdesk]

Original post:<br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=021463 <br /><br />Now I learn more from the mechanic: Even though they told me before that the cylinders are scored and the reed valves are broken, they are now telling me that they haven't taken it appart enough to know for sure, but apparently were "assuming" these were the problems based on poor compression in two cylinders, with "blowby" coming through the carburator (something like that). I'm not exactly sure what that means, but apparently either the reeds or the cylinders aren't holding the pressure. Obviously one is a less expensive fix, and the other is more expensive. <br /><br />Now they are asking me if I want them to continue tearing it appart to really find out what the problem is, or if they should leave it as is, and let me have it back. So far I can't get them to estimate any costs for me.<br /><br />Any advice? I had the impression before that the motor was appart and they knew what was wrong, now it sounds like they have only done compression tests. Should I have them tear it appart and see what is happening? What could I expect that to cost? I think I could do it myself, but I don't have micrometers etc, could only give it a visual at this point.<br /><br />Ted

If I had a failure diagnosed based on guesses, adn the common failures of a model, I think I´d want my motor back. It would be more fair if they admitted they hadnt had the time to look into it.<br /><br />By removing both cylinder heads and inspecting cylinders and piston tops you will know a lot.<br /><br />Maybee you only need a couple of decarbs, and its running again.

Yes, Dane, I'm feeling like they haven't been very honest at this point. At the vary least it's been poor communication.

Poor communication at best!<br /><br />For someone who wants you to trust them and give them what could be a lot of money, they dont seem too concerned or interested. <br /><br />If it were me, I think I would take it home and, as suggested, do a good decarb. Thake compression now and again after the decarb. <br /><br />If the heads have not been off in a while, you might want to consider that at some point just to replace the deflectors anyway.

I'll be down to get my boat back as soon as I can! After all the mechanic did say he didn't think it was worth fixing, so I don't see any point in pushing him to do anything more! I'll have a look at it once it come back, and see what I can do from there. I'll do the compression checks and decarb. I'm sure I can replace the leaves myself if that's what is needed. I'll also look into the deflectors Dhadley.<br /><br />Can anyone point me in the right direction for getting used, affordable leaf valves? I guess I'll probably be looking for a powerhead as well at some point, though hopefully not for a while. Any advice on businesses or web sites that provide this would be great. Thank you.<br /><br />Ted

Lets see what you got before we spend money. I doubt the stock reeds are broken.<br /><br />Let us know what you find when you get her home.<br /><br />Good luck!

I can't understand how the guy can say the reeds are broken and the cylinders scored without taking it apart and looking at the reeds and pulling the head and looking at the cylinders. I doesn't make since, I had the same thing on my 74model when i first got it, shop said the same thing, I told them dont touch it because the cost was way more than the motor was worth took it home and did what im going to tell you, Walla after the dcarb the compression was back up and no problems for 5 years now, don't get antsy the compression didn't just pop back up it took about 3 bouts with the decarb before it did go get your motor back and pull the heads you can tell if the cyl. is scored, if not pull the intake check the reeds you can tell if one is broken, if nothing get new gaskets put it back together and dcarb the heck out of it my guess is you will find gummed up reeds and carboned up or stuck rings. Good luck with it, why pay those rip offs $1000 when you can do the same thing for $50. Again good luck.

Thanks Bass Runner. I hope I'll have a success story like yours! I sure will do the decarb in a big way, already have the seafoam on hand.

I was on ebay less than an hour ago looking at what ends tonite and saw a set of reeds for a 135 had not been bid on yet, starting bid was 5 bucks if memory serves. You had better hurry though as it was getting close to ending.

Thanks for the heads up on that. I contacted the seller to find out a little more. He said he couldn't get the seriel number to me till tomorrow, so I guess he'll relist it. Do you guys think this would work for me? It's sure cheap enough! Would really appreciate any input. Thanks.

I am not sure if it is same as your's or not, I was thinking that '73 was electiric shift but not sure. The same guy had the block listed as well and it didn't get bids either. I don't know if it came with pistons, rods or crank but he started it at $20 no reserve. Maybe if the parts will interchange you can get the whole thing for a song and make one decent for a few more years motor. Just a thought, sounds like a fun project to me.

Re: Update on 1973 135hp that's in the hospital

Yes, maybe I can! I've e-mailed him to find out more! The pic of the block looks rusty, but it's hard to tell. Hopefully he replies soon.

If you want to replace the reeds get a manual first. Remember to lock all screws in there and at airbox, they just dont like chewing screws

Im sure qualified marine maechanics hate to see things like this. I recently had to take my engine in for a repair, and it killed me to have someone else work on my engine. I knew the guys and trusted them, but I like to do things myself so I know what Ive got and that things were done right, or even done. Needless to say, I have been ripped nearly everytime I let someone else work on my stuff. You have been lied to and deceived, you have got great advice here and I think your engine is going to be purring in no time. I personally very much doubt that your reeds are bad. I think the decarb is going to fix your problem, but like already mentioned, dont expect it to happen with the first decarb, you may have to do it several times, the longer you let it set with the sea Foam in it the better.

I just got the OAM service manuel about a week ago, and am really happy about it (it's actually the Johnson one but I understand it is identical). I have been reading it every day just to learn how everything works. I can't believe how detailed it is. I know it's going to be a lifesaver.<br /><br />I started a new post about some things I found on E-bay, but maybe I'm jumping the gun in trying to find parts before I find out what's wrong. I guess I'm just a "deal hunter" and saw these listings for so cheap that I couldn't resist following up. Seems that it might not hurt to have spare parts just in case . . . .
