OSE Mini Outboard Seizure
G'day Guys,
Last week I bolted one of these legs ( http://www.offshoreelectrics.com/pro...prod=OSE-80980 ) to one of my F1 hornets.
My leg is a bit different from the one pictured on the OSE website. ( Different motor mount and an extra brass fitting.)
After some mucking about setting up an acceptable pushrod setup (600 heli ball joints/pushrods and some modified nylon control horns) I dropped her in the dam last night.
Power was great, motor stayed cool and battery/esc temperature was ok. Things were going great for a few minutes, and then I lost drive when the flex snapped.
I launched my inflatable and recovered the Hornet to find that the propshaft was seized solid. ( I'd lubed the flex before putting the boat in the water.)
I needed vise grips to liberate the prop shaft frop the screw in bush at the end of the leg. This bush isn't brass, and appeared to be "welded" to the steel propshaft. ( I've attached a pic, the bush looks like copper.)
With the inspection plate removed there appears to be a 'total loss' lubricant reservoir above the flex shaft, fed at the top with a barbed brass fitting and draining at the bottom with a small opening presumably to lubricate the prop shaft bush.
I've deburred/polished the inside of the prop shaft bush with some abrasive paste and my spare prop/flex shaft shows no sign of any binding.
I'm about to reassemble the leg to try things out again and was wondering if anyone else had played with these legs and had any issues.
I'm going to try some synthetic engine oil in the reservoir, is this the right method of attack? I've got a fair idea about things that fly ( helis, sailplanes, airplanes and multi rotors ) but I'm a newbie when it comes to boats so any advice is welcome.
