I was out on the Occ Res Saturday with my son. It was cloudy early and took a lot longer to warm up than I expected. My little 5hp Eska Ebay special has stopped spitting water. Every time I stop I get a small cloud of steam. Once I noticed that I wasn't spitting, I only ran the motor for short ~5 minute spurts to the next likely looking spot, and gave the engine a chance to cool down.
I heard that the small Eska's (which I have the Sears version of) can actually run without the impeller working.(another poster on iboat said that Eska actually states this in early printed material). I felt the engine and it didn't feel very hot.
I don't know if this is true, and I plan on figuring out how to replace the impeller. It looks like there is one large machine screw and and one large bolt holding the bottom piece of the leg on just above where the propeller comes out, and just below where the water goes into the leg (screw and bolt facing upward toward the head). Unfortunately the large screw is a simple regular head and is stuck fast, and I can't figure out how to apply some real torque without stripping the head. On the couple of attempts that I tried, the screw driver slipped out of the slot and I can see that I have just started to strip the slot. One thought I have is to actually epoxy the screwdriver into the head of the screw. Once I have the screw out, if I can't get the epoxy off, its a simple task to get a machine screw replacement. Its a stupid design, they should have had two bolts instead of one of them being a screwhead.
If anyone has actually replaced the impeller on a 3 to 10hp Eska (or other small outboard in general) please PM me with any further info on the subject.
Any way, back to the subject of fishing, I asked the oldtimer at the rental desk what was working. He said that because the conditions are cold muddy high water, that I should try going all the way into the back of the shallow bays. He said the muddy shallow water gets a chance to warm up under the sun faster than the deep water and the bass like it there. He suggested white spinnerbaits and to even try a buzzbait. Tried what he suggested without much success.
