Weird, I THINK it was vapor lock. Someone said remove the gas cap and try to run it. It stays running! Hoping it stays this way now.

So it was suggested I ensure battery is fully charged and charging working first. I put the charger on over night, just tried boat again this morning. Voltage reads 11.9V with engine off, reading 14.4V when it's running, so everything seems fine there. This time, I timed it while running, 35s first time, then 40s, then 38s so it seems to run 35-40s. Only this time when it shut down the 3rd time it didn't necessarily sound like a quick shutoff, it sort of sputtered off briefly. Should i order that valve? Any ideas? I do keep getting some trouble codes when I start up VesselView but I don't think any are relevant to my boat so I've been ignoring them. Inserting in case.

Hi all. 2006 Avy, Black Scorpion motor. Ran great last summer, winterized for a couple months. Brought it back out, de-winterized, did oil change. Started boat with fake-lake as usual, boat runs for a # of seconds (I would say about 8s, but it seems like it's the same amount each time) then just shuts off. Runs great while running, smooth, and just shuts off like something is telling it too, not like a sputter or something mechanical but more like a signal or as if you just turned the key off. So, I went through the remainder of the maintenance schedule, new fuel filter, new water separator, and new spark plugs too. Same thing. Runs great, X seconds, then shuts off. Hooked up Vessel View, no codes. So, July of 2019 I replace my IAC valve, the boat would die every time I dropped back to idle while moving, or just not idle without a little throttle when first warming up. Fixed the issue. Fast forward back to today, I read on this issue and keep getting IAC valve again! But it's only got a year on it. I saw a "test" to give it throttle in neutral after it starts to see if it stays running that way. It does, over the normal shutdown time, but it goes up and down. Meaning if I set it at 1500rpm, it will slowly fluctuate (over about 3s) between 1200 and 1500, but not shut off. Go back to idle, wait the x seconds, shuts off. Sound like IAC again? I did buy the cheap one everyone uses form Amazon vs the OEM one. I'm trying to just get this thing going again without an arm and a leg because I'm trying to post it for sale! Thanks.

Got a VesselView Mobile, this thing is awesome! All the info, trouble codes, engine hours, etc for ~$300, was the idle air control. Thanks!

This? https://www.amazon.com/Idle-Air-Control-Mercruiser-862998/dp/B01NAO6YE8 Can I check that first?

Oh, BTW, surfers... I'm going out tomorrow with the family. One thing I have not moved since I got the boat, the trim tab. Where do you position it for surf? It's the manually adjusted center tab, it's pretty much flat right now. UPDATE: Hmm, I guess it's not adjustable. I assume it was because there are what looks like adjustable lock nuts on the posts, however, the plate sits in a recess in the hull screwed on with 4 large allens. It looks like the supports are just supports, the plate is not adjustable?

Found the correct shocks, not sure why I didn't think of it before but they are the same as the storage hatch/seat! For others, here is the part and they work great now! GSNI-5200-60 Now to figure out the idle thing, thanks @Creekrat82, that will be my next task to try!

Anyone yet? I need to order these today. I used this: https://www.boatingmag.com/installing-gas-strut-hatch-supports#page-5 And then estimated weight by materials (weight of 3/4 plywood, 1 yard vinyl, etc). I got ~25lbs for the hatch so ~42 lbs of support (or 2 x 25lbs let say). Measured and they need to be ~15" open and 12" closed. That seems too light to me.

Thanks! If I can order tonight I can overnight some. I think the weight was off too, there were 2 60lbs on there and 1 held it up, so maybe that helped rip the screws out.

Bump, anyone? Planning on heading to the lake this Saturday, like to get new supports ordered/on asap! Thanks again.

Hi, search and didn't find anything yet so given I have ongoing fixes, etc with my boat, I am starting a thread. Right now, I'm working on my engine hatch which the screws gave out on and my idle issues, so I have some questions. I fixed my hatch so that's mounted again, however the lift support towers had to be fixed to and in the process, we found they were moved. We re-mounted them in the original locations but I think the previous owner also changed the lift supports because now they seem too long. Can another Avy owner with stock supports tell me what they are? I have the black scorpion. It idles fine once warmed, but when started cold I have to give it some gas to keep it running and "warm up". My parents boat has the same motor and never has this issue. What do I look for? I've changed thermostat and water fuel filter, still need to change the inline filter which I plan to do tomorrow, could it be that? Thanks!

BTW, clearly says "Velvet Drive" on the first component with the pinkish dip stick and pinkish fluid. This "box" in question's dipstick says "Walter" on it and the fluid on this stick looks more like oil, very clear with no pink tint.

New question everyone, thanks for all the help with the new ride! Almost ready to hit the water this year. Something that's always confused me because the book (parents anyways) doesn't show it. I need to do a transmission (v-drive) fluid change. I believe the transmission is the pinkish dipstick that you turn to release the rubber plug, first item after motor. So what's the last item? Behind that is the box where the fresh water first runs through, it also has a dipstick in it that just pulls right out, very short, top right side. In the pic I'm attaching, you can see half of this knurled "dip stick" in the upper right in the "box"

Well I tore the whole cooling system apart. There was water everywhere, thermostat moves, impeller looks great. I think maybe it was just a combination of the fakealake and myself being cautious and shutting it down too early. Going to replace both the thermostat and the impeller anyways and keep the current impeller as a emergency backup. I'll have a look at that t valve mod too. Different issue I can't find anything on, maybe you all can help me with. When I first start it up I have to have it in neutral and start it at a higher RPM or it will not stay running. Once it warms up, not long, maybe 20 to 30 seconds, it runs and idles just fine. It's as if there's a choke system not functioning properly. I've never had this issue with the same engine on my parents boat, starts right up and Idols even after coming out of winterization.

Ok thanks guys. I hate the impeller job on this (done it a few times on my parents boat), they put it in a crappy spot. Guess I'll start pulling hoses and pumps though and inspect everything! I was hoping the belt was all so I could move on for the season. Maybe there's a pump relocation/electric for this thing...
