Blew up my Merc 135 - gonna be an expensive boomer.

During one of my last outings on the lake I detonated a grenade in my Merc 135. Here are some pics of the damage. I put a rod through the block which then proceeded to split the throttle arm in two. I just started tearing it down today so I haven't seen the insides yet but I'm seeing some hints of water in the oiling system.

As most of the boat guys on here know, blowing up an outboard can be a LOT more expensive than blowing up car engine. Short blocks to replace this Merc run about $4K and up...and that's with me doing the install. If I hadn't toasted the block I probably could have just done a major overhaul for less than $2K. But this little episode is going to put a dent int the checkbook.

This pic shows the the rod and the hole in the block (arrow).



Here's a shot of the damage done to the throttle arm (arrows on right) and the rod (arrow on left). Those two sections of the throttle are are supposed to be one.



And a close up shot of the hole in the block.



Sort of makes those walleyes a tab bit expensive.

Yes. I was at full throttle and doing about 50 mph when it happened. I heard it snap and then it was just me and the loons slowly floating around in silence.

BTW, it was a LONG row back home since there was nobody else out on the water to give me a tow.

yep, boats are usually cheaper than the engines.. That's kinda ugly

Check with a boat yard and see if they have a boat with a decent motor but rotted transom.. Merc 135 is quite common, but anything in the 130-175hp range should work as long as you get controls and the shaft lengths right.

Oh my - what a day!! But that's what winters in the North woods are for - repairing your "tools" for the next summers outings.

The worst I've done with boat motors is to replace the $1300 bottom end (2x plus one total rebuild) on my old 6 cyl Merc 115

Knowing you, Dewey, a couple of hunks of aluminum, Maybe from an old intake you melted down, a Dremel, a drill, and some sandpaper and you'll be back on the water....

I have a Mercury 200 Horse Pro Max on the back of my Gambler. It runs good but it`s given us a fair share of trouble. I`ve rebuilt the foot in it twice now.
Other times the engine itself hasn`t given us much issue, cept the oil injection pump went out so we started doing pre mix. I told my brother I wished it would have came with a Johnson outboard or Evinrude. He asked me why and I said "A old timer told me, and I`ve seen it`s true countless times now, If you wanna go fast you buy a Mercury, if you want reliability you buy a Johnson"

Outboards

I'm guessing that the long row back home is a pretty good secondary argument for so many guys that I see having a 9.9 horse trolling motor back there alongside the prime motivator?

Second kicker

Maybe the popularity of the 9.9 around here as a 'kicker"/trolling motor is due to a peculiarity in local laws. If your boat has 10 hp or more, it has to have a registration number. Under 10 - no "reggy" needed. So there were a LOT of "9.9" hp trolling motors sold for the car-topper/row boat/small fishing boat crowd - and they were so popular that they now appear on EVERYTHING. Even the guys with inboards and with big out-drives hang a 9.5 or a 9.9 out back somewhere for trolling without having to use the "big boy" at idle all day and for getting home if the big boy craps out.

(My first boat was a car-topper with a 2.5 Evinrude)

Normally I would at least have had my electric trolling motor available but I had removed it to do some repairs and went out on the lake without it. It was actually fortunate I even had a paddle...I had thrown that in as just a last minute afterthought.

I'm heading over to my local Merc dealer today (where I originally bought the boat) to see if this rig is even worth the effort to repair or if I would be better off selling the boat and salvageable motor parts (bottom end, heads, carbs & reeds, etc) and investing in another alternative. Unfortunately, this is the boat I just totally reupholstered and painted last season, so now it looks great but without a running engine the resale value goes into the dumpster (at least around here).

Dang, Dewey, that's a bad arse looking boat, I would cry if I had to part ways...unless this is a good excuse to go boat shopping? A guy living on a lake NEEDS a boat, otherwise you may just as well live in a van, down by the river. Good luck with the search, if a guy is hard up for bucks, this may be the perfect time to buy a boat with a good motor, change it over and sell the leftovers, may be able to recoup some of the money invested. Walleye season is still 4-5 months away!

If any of you guys have never eaten Walleye, it is the fillet mignon of the seafood world. If I don't get a Walleye dinner when I am back home, it is a busted trip. All the more reason to get the boat running, last time I bought walleye to bring home, it was $8 a lb.(1991) and I would bet a buck it's at least $12 now.
