Question about the impeller: Does it matter which way it goes in?
When I took mine out today I looked closer at it and on one side it says Johnson and the # and the other side it says nothing.
The splines on one side (don't remember which side it was) come all the way out to the end of it and the other side there is maybe a half inch gap before the splines start.
I'd imagine it would only fit one way, but figured I'd check.
Mine was in with "Johnson" side facing towards the back.
Thanks

I decided that Johnson would put their label and the part # so that it would be visible when u pulled the impeller cover so that's how I put it back in earlier this yr and it worked fine. I think it goes in both ways and I don't think it matters which way u put it in.
If anyone knows any different, please let us know.

Cab, and all, have any of you ever taken the top cover off of the V-drive in the spring to clean it out? The Walters V-drive manual says to pop the top (I think it says 6 hex head screws) and vaccuum out any particulates that have accumulated. It would just be the small area where the cooling water passes thru to cool the fluid in the pressure lines. It appears, from the schematic, that this pass-thru area for the cooling water is pretty small, and I can't imagine too much getting caught in there.
On another note, once I pulled my impeller this year, I found most of one paddle almost completely gone. I read several posts on worrying about pieces possibly passing thru the engine. Thinking of this, I pulled the line that goes into the in-line transmission cooler, and wouldn't you know it, there was the piece of the paddle, and some additional junk. Luckily, it let me know that for anything to pass thru that cooler, it would have to be fairly small. It also made me realize that putting a stainer on the cooling water intake might not be a bad idea, since with that piece of paddle I found a whole glob of accumulated seaweed.
I bought the boat used this year (it's an '08) and I could tell the impeller hadn't been pulled before. Thankfully I did! Bummer that it had a paddle gone already, but, I think whether you leave it out over the winter, or leave it in, pulling the impeller each year is a good idea. That, along with the inlet to the transmission cooler just to make sure nothing is in there, and the cooling flow is strong.
My Walters V drive manual does not say to pop the top and neither did the service guy at the dealership who showed me how to winterize.
Yeah, for the 5 minutes that it takes, I pull the impeller every winter. I'd rather do it at my convenience rather than on the water with a boat load of people.
Popped the top off my v-drive last year. Very open path for water flow and very little buildup so I don't think this needs to be an annual check. Gasket was extremely thin paper and not reusable so used RTV. Also replaced the original bolts with anodized because they were so rusty. Plan to pull the bottom off this winter and make a new gasket to see if this stops my oil leak.
If one doesnt have a fresh water strainer I would recommend checking/cleaning the Transmisson cooler at least annually. There is a screen in there and can get blocked.
It is a easy mod to added a fresh water strainer. It was one of my first mods and glad I did it. Do search for fresh water stainer to see the before/after. The parts were less then $70. Here is a link to my project thread https://forum.moomba.com/showthread.php?t=7597
I agree with that. The piece of mind that comes from knowing you've got a filter cleaning that water is one less thing to worry about! I plan to throw one of those in this spring!
Going to winterize my LSV this week. I have 06 LSV with EFI 5.7L 340 EXT/CAT. Asside from the no flame arrestor and fogging the cyclinders thru each spark plug, is there any other deviations from this procedure that anyone has noticed?
If you have a heater system you need to blow the water out of it. Al's boat doesn't have a heater yet. Mine does, there's a line at the water pump area and the other part is by the Starboard exhaust manifold, you need to remove these and blow out as much water as possible.
Other then that Al's write up is perfect.
on my 340 cat the heater hoses are on the port side , its an 09 tho, how do you like the tsunami? have you ever tried a ride? thinkin of getting one for the newbies they are suppose to be faster? anyone know if they are?
