Douglas,

Me? I've had more than one motor adventure lately, could you be more specific?

<center>1992 Yamaha 9.9HP extra long shaft, high thrust</center>

Engine had been running poorly until warmed up. Sort of like running on only one cylinder, but not quite, and there's not much that can affect only one cylinder on these motors. Also noticed a very slight oil leak at lower unit while lifting motor back on to newly installed motor mount.

Bought seal & gasket kit ($65 or so). Tried unsuccessfully to get access to seals in lower unit. (A long story of strange design and special tools.) Called Yamaha repair shop, was quoted one to two hours labor to change seals. Took lower unit to Yamaha repair shop, along with spare lower unit to use as parts donor. Confirmed one to two hours labor estimate (@$65/hr), plus $25 to heli-arc bite-sized chip in cavitation plate. So that's $90 to $155 (plus the $65 I already spent for a seal kit). Was told job would be done in a week. Said, "OK, but don't run up a big bill on a 10-year old motor." Emphasized that the only reason I was bringing it there at all was the need for special tools to avoid damaging lower unit.

A week later, motor not ready. Drove down there to check on it. Both lower units had been burned almost beyond recognition with oxy-acetylene torch in futile attempt to dissassemble without special tools. Several parts destroyed. Replacement parts on back order (at my expense). I once again reminded the mechanic and owner not run up a big bill on a 10-year old motor.

To make an already long sad story a bit shorter, about a month after I first dropped off the lower units, I got them back, one still burned, one freshly painted, for $368 (plus the $65 I already spent for a seal kit). I was not happy. The owner hid in his office when he saw me come in the door. The mechanic stormed out the door and squeeled off in his 4x4 while I was still just starting to explain how unhappy I was. A week later, the paint job started to crack and craze.

As for not running right when cold, I diagnosed it to probably the (non-replacable) plug wires, maybe the coil, or (long shot) the CDI black box. After pricing new parts (around $300), I hunted down used ones ($120). I installed the used parts while bobbing in my dinghy with the boat in the water. Problem solved. Old parts now in spares kit.

<center>199? Honda 10HP long shaft</center>

While the so-called mechanic was f'ing up my lower units, I perceived the need for a backup plan. I have a pile of about five dead Honda outboards. In rooting around in the pile, I found a 10HP that sort of ran, but had low compression on one cylinder. To make another long sad story shorter, I broke the engine block while getting the cylinder head off to do a valve job (salt water motor).

Back to the engine pile. There was a 7.5HP Honda, without a head, that used to turn, but had since locked up. It's shift shaft was also locked up. I sprayed penatrating oil on the pistons, and applied a fearfull amount of torque to the flywheel nut while pounding on the pistons with a padded hammer. (Does that sound Neanderthal, or what?) Suddenly the crank spun freely. No drag. No scars on the cylinder walls (the pistons had been at TDC). No hint of why it had been stuck. Very spooky.

I extracted the shortblocks from both engines (breaking only a few more bolts in the process -- salt water motors, remember), stuffed the free turning 7.5HP block in the 10HP engine, finished the valve job on the 10HP head, and threw the whole thing together. It started and idled on the second pull.

This entire Frankenstein's motor resurection took about two days, while the Yamaha butcher was still waiting for parts to replace the ones he'd ruined.

<center>Minn Kota 24# 12V trolling motor</center>

Former girlfriend left an old trolling motor in my garage when she moved out. Dusted it off, stuck it on my plywood dinghy along with one of the group-27 deep cycle batteries from my C-25. Went canal cruising for a couple of hours at hull speed using max power. Hydrometer showed %75 charge remaining. So that motor adventure was a happy one.<img src=icon_smile.gif border=0 align=middle>

Jeez...I should've bought Honda stock!

That saltwater must really wreak havoc on a motor? <img src=icon_smile_shock.gif border=0 align=middle>

Umm, well, it seems that if I sit my big friendly cat on the front seat of the dinghy (with a harness and tether), and slowly drift past waterfront bars, it tends to atract the right sort of attention... <img src=icon_smile.gif border=0 align=middle>
