Re: jet vs. prop

sxpack<br />I like jets myself for the ease of running in shallow water. And a heavy Alum hull! <br />But check out that website seahorse left.<br />Every year we go fishing on opening week on Swift Res down south of us. My little Almar (made here in Tacoma) sled is to small for the 3 foot white caps in the late afternoon so we just hug the edge of the lake a couple feet off shore and scoot home back to camp.<br /><br />Link

Re: jet vs. prop

I have an outboard jet. If your using the boat on fastwater, shallow rivers, you have to have a jet.<br /><br />Deepwater, I'll take a prop.

Re: jet vs. prop

getting in close to shore, wouldn't that cause a lot of the sediments be sucked through the jet? Especially near the boat launches if there is not a concrete ramp? Lake Ohop (Eatinville) and Tiger Lake (Belfair) are the two lakes I will mainly go. Tiger Lake's Ramp is all gravel and near the shore around most of the docks, Lake Ohop is soft. I did not have a lot of power, is that due too the fact my impellor shell is below the hull causing too much drag? 85hp suzuki

Weeds will clog the inlet. Dirty water isn't an issue, but abrasives are.<br />It's safe to idle through water that gives you 12" of space between the pump inlet and sand /Gravel. On plane or WOT, 6" won't pose a problem.<br /><br />The leading edge of the shoe should be even with the bottom of the boat. I've experimented with mine. 1/2" above, gives me 3mph more but cavitates under acceleration. 1/4" above, gives me 1MPH, with no cavitation, plus extra clearance.<br /><br />Your 85hp is now actually rated at about 60 at the nozzle, with the pump.<br /><br />Sucked in a bunch of gravel last weekend. Fourty bucks for a new liner. Came in today, will take 30 minutes to install and shim.

Re: jet vs. prop

To answer the first question it depends on the waters you will be fishing. If its rocky and shallow use a jet. If you'll have deep enough water and no rocks to be concerned about, a prop would suit you best.<br /><br />You'll lose 1/3 of your HP with a jet pump. <br /><br />With my 115/80 jet I only need 4" of water when on plane but if I am wallowing along I need a foot or so. If you have a prop you best have more than a foot of water under you.<br /><br />To respond to the comments about sediment, etc, if you're in a position to suck that much you are in a place where a prop does not belong. Its easy to trim a jet so as to avoid sucking sediment, else use a push pole. If you run a prop through that shallow of water you'll have no prop in very short order (unless you break your shaft first).<br /><br />Lastly, if you use a jet I recommend a stainless steel impeller rather than an aluminum one. Not only will you have better hole shots (stainless have 4 fins and most aluminum ones have three) but the stainless will not be so sensitive about sediment.
