Re: lower unit removal
ok now i'm really confused. I'm thinking my DVA doesnt work- at 1000 VDC, i get a reading of 7 on both blk/yel and blk/wht, both drop as revs increase. As far as resistance, i'm not getting anywhere near the readings i should be. All that aside, i tried the tach on the upper cylinder again- it's reading double what the lower cylinders rpm is. So, i decided to try to switch the coils around but my standard sockets didnt fit so i ended up swapping trigger wires and then plug wires. Now both cylinders are showing the same rpm's- right around 5100rpms at WOT, might get more with less weight. Here's the problem. Even with both cylinders firing, according to the tach, i still only get 10km/h on the water. Everyone i've talked to says my 25 should make my boat jump out of the water. As i was trailering my boat after testing, an older guy driving by stopped to chat. He said he used to own a boat just like mine. Perfect. I asked him how it used to move on the water and found he had a 9.5 on his and said it was great. I told him about my top speed and he immediately told me I had to be waterlogged. He said the 25 should make that boat fly. He then proceeded to tell me about a couple of boats he'd owned that he had to rip the floor up and remove a type of foam flotation material under the floor that had become waterlogged. Apparently, there's no way to get the water out once it's in. I was all set to drill a hole to check for this foam when something occured to me. I told him that my 40lb thrust electric motor could move the boat 1/2 the speed of the merc at WOT. That changes things completely, doesnt it? there's no way that a 25hp motor should have so little power. So what do i do now. I have no ideas anymore. it seems to run great, just absolutely gutless. Appreciate any further help you can offer.
