Fake-a-lake question.

[Skagit]

Hey all-

I'm going to run the boat in a tub this weekend (I just can't trust muffs...I was attacked by a dog wearing muffs as a child). I have a container that should work (big rubbermaid tub) but I want to make sure it's deep enough. What part of the lower unit needs to be submerged? It's an alpha one. There is a vertical line of 5 or 6 holes, which I assume are the intake ports. Then there's a horizontal ridge or strake, and then one more hole on each side...does that top hole need to go under or is it that an outbound port?

Other than that...don't put it in gear, keep the hose on so the water doesn't heat up, keep the RPM's reasonable...any other things to keep in mind? Is it loud?

Thanks guys.

Re: Fake-a-lake question.

The holes are the intake for the water. Be sure that that the water does not drop below that level. Also, dont run the rpms very high and you will not be able to put the boat in gear. If it were me I would get a new set of muffs for $11.00

Re: Fake-a-lake question.

I wouldn't do it. You need to have enough water to cover the cavitation plate by a few inches, and I can't see you being able to do that because the rams will hit the tub right at about that level. Then, once fired up, water will be a flyin! Sounds like a big messy hassle to me with a lot of risk. Muffs if duct taped in place when the lower unit is dry really are the safest way to do this. The hose water pressure means the pump won't be dry on startup and will get circulation through the motor faster. It will be loud on the muffs, but it's a "pretty" sounding loud.
Get the muffs.

Did you know that Fake a Lake is a brand name of "muffs" for inboard boats?

Don't try to re-engineer something that doesn't need it. Use the proper tools for the job and putting your lower unit into a barrel is not the proper way of running your motor. Pull your head out of your butt, get some muffs and do the job correctly.

I don't usually respond to unprovoked insults...but screw you, jerk.

Anyway, back to my question...

I've seen alot of talk in the forums about running I/O's in a tank. The guy that did my survey did it, so I didn't think it was a big deal. Seems to me six cubic feet of constantly refreshed water around the drive would be closer to operating conditions than a little stream from my garden hose.

Not a very nice response, Crusader. Apparently you don't know it all, either.

I have a 100-gallon Rubbermaid watering trough that's deep enough for the LU on a 175 Johnson looper. Not only does water cover the intakes, being able to submerge the leg also introduces exhaust back pressure. That can very handy at tune-up time, and not something you can accomplish on muffs. As far as water flowing out of it, simple to compensate for by letting the water hose trickle into it.

There can be more than one proper tool for a job. The OP merely needs to insure that the intakes are covered, whether on muffs or in a tank.

I didn't know that, but you have 5 boats! That's awesome!

Re: Fake-a-lake question.

Personally I think running a motor in a bucket is the only true way to test your impeller/cooling system. Well 'sides running it on a lake, etc. When the muffs are on you're relying at least in part on psi from the water supply. So long as you have the lower unit submerged to the cav plate or so. And adequate hose pressure to keep the tub full. Go for it!

Nobody said ya have to put it in gear. But just for gits'n shiggles I probly would too ...

Ihave aTrisionic 72 that takes water in from the bottom. the problem is the intake is too big for the fake alake. Now what do I do?

I use a plastic trash can, standard muffs wont work on mine.

How large a diameter inlet is it? The fake a lake is the size of a toilet plunger, hard to imagine an intake that would be bigger than that.

Re: Fake-a-lake question.

the intake has a screen with fins on it. when you look up the cavity you see a impeller and a closed door . it is jet pulpulsion. It does have a strainer with a removal top in the engine area

Ah - it is a jet boat. I can't think of any way that to run a jetboat off a hose since it steals water from the propulsion intake. Fake a lake is for inboards.

Re: Fake-a-lake question.

Have a look here on page 10. They list some sort of a procedure - assuming you have a berkely drive

Re: Fake-a-lake question.

Using a barrel is fine, but you need to be aware of the possibility of burning up your impeller if the water isn't deep enough. The impeller in an Alpha is just above the cav plate, as long as your close you should be okay.
