First post here so sorry to be starting off asking for help!
I'm Ed, I bought a Bombard Explorer 5.5m with a 50HP Honda, 4 stroke about 6 weeks ago to use as a general safety boat while the kids are sailing and for a bit of fun.
When we took the boat out the first time we realised there were a few issues, mainly the engine was working on two cylinders, there wasn't any water coming from the tell tail and it seems to accumulate some water in the hull.
I took it to the boat yard and gave the ncie chap a cheque to get it all running well. He sorted out the engine nicely with new carbs, a full service and new impeller. The old one has 3 of it's 6 vanes broken.
We've been out in it a few times and we're happy. I took it out last night but while not paying enough attention we went through some mud as the tide was quite low. The engine was pumping out water beautifully before with a good strong tell tail, it's now a bit of a trickle which increases in strength as the revs rise.
I suspect maybe I've just sucked up mud, but I wonder if I could have damaged the new impeller?
What can I do? the boat is currently on it's mooring and I'm keen to try and solve this myself if I can. I've just read advice about putting strimmer wire up the tell tail to see if there is a blockage, is it worth trying? Or do I really need to take the lower unit off to get at the impeller? Could it just be that a few of the vanes are full of mud so it's only pumping on two?
Oh, and in the mud there must have been a stone as one of the prop blades is badly bent, looking around i see adds for BF90 props? Is this what I need of the engine?
