Don't need to seal the edges. Just put sealant around the cover plate. Disconnect battery with hatch open. Sender has a gasket no sealant needed. I used a power screwdriver with a nut driver and alternately tighten nuts. My tank was full also. Use a shop vac as you drill if you need the access hole. Wipe the top of the tank off before you remove the old sender. Probably getting the screws started by hand is the hardest part. Takes a little feel and patience.

Thank you very much. I was at boat yesterday and there is an access port, just a crappy cover plate with four screws and two crack. I'll be installing a spin open with a seal. Seems like this was a water incursion spot. Hosing the deck and water would go in under that storage and run over that plate, thoat surely leaked.
There is another drain area under back seat too. If you hosing out storage there's now direct path for water/debris. It pools there and also in trunk as well. Did u do anything to increase drainage?

Yes. I just mounted the switch to the back of the tv. I leave it on all the time anyway.

What did you do with the light switch, just behind the tv?

Waste hoses question.greenw/white stripe brand
Looks like mine are aged, prob originals from 06, cracked along the bends in hoses. I ordered a replacement for the easy one from holding tank to discharge seacock, thats a no brainer. However the other section from the head to the holding tank is in same condition.
Has anyone tackled this replacement? The hose runs through sections that looks to be contained in spray foam sealant. Know how much fun that stuff is. i know external cracks dont mean leaks, but prob fume permeation.

Took delivery of new to me 03 last night. Had a 30 minute ride to our home port and everything went well. Was just the admiral and me on the boat for the trip home and we were sitting up front. When we finished our sweatshirts which were left on the aft u seat were soaked. Looks like we took a lot of spray over the back into the seats. Is this normal ? Do I need to be always be fully trimmed down ? Does the low swim platform drag ? Just wondering if we had passengers in the back while on plane I assume they would have been wet also. Was cruising about 19-20 knots and there was a little slop in the bay. Anyone else have this experience? Thanks

I was not able to reach either. I ended up installing an in-hull transducer, P79?, to work with my Simrad. Installed on the hull inside the cabin where the Sump box is, right at the foot of the stairs. Part of that area by the sump is sloped, so installed it there. Ran the cable up to the bow by the AC under the bed, then over to the Starboard side and all the way back down to the Master AC/DC panel, then up to the helm. That was fun. I had to cut the connector off to make it easier to run. Just spliced them together, no issues so far.

You also could have run a NMEA2000 backbone..hooked up the smartcraft system to it and the Simrad and the Simrad would have picked up the transducer...

No that is what my issue is. I loaded the app put in the information for two engines and my fuel tank size then I get the error message that one of my of my ignition systems needs to be turned on.

Did you have a mercury dealer reset the port engine, all engines come defaulted as starboard. I was told by Mercury to do that to get both engines to display properly.

And here is a pic I took of the tool:

The pad on my port side vibrates with the new JL audios speakers I installed, I noticed a fastener broken, are those easy to find/replace?

I have found that either the swim platform or just the general angle of the boat while cruising causes some misting blow back in to the lounge area. It is usually a fine mist but it will collect and get u wet eventually. After every cruise there is a fine film of salt on the entire back of boat, like a glazed donut. Im not sure if its my trim level or just inherent to the boat and weight. The generator of course is a heavy item.

At that speed you are probably dragging a little in the water. Speed her up a little and then trim her and you should not have that problem.

I have not had this issue, same boat, v-drives, same boating area, Tampa, and even when a bit of chop out, the boat does not get wet in those back seats... now, if the wind was blowing 15-20, coming directly behind you, or off the starboard or port stern quarter, then maybe.

 

[Todd320]

Here is what my wake looks like, this was a smooth day. I usually go 21-22 knots...

Hello all, new to the forum as I am in contract on a 2003 320. Had the survey yesterday and found some items to address. One issue that I wanted to check on, we had water in the mid-ship bilge (bilge pump was not working = the issue). The one with the shower and AC box / bilge. I would think this bilge should be dry. Wondering if we can find where the water is coming from. It may be coming from the shower / AC box leaking but the water would have been there from last season than since the AC or Shower has not been used yet this year.

I have has issues with that same bilge. 05 320. I have two pumps there, one in the shower sump and one outside in the lower level. I replaced one pump with rule auto sensing two years ago. It died and i got a new one and replaced it last year. I took entire sump box out last spring cleaned entire area, sump box etc. Pump was working in the sump. Then mid summer both pumps went out and flooded again. That did it for me with the auto sensing pumps. I just had my boatyard replace both pumps and the external one with old fashioned external float. Hopi g for a dry year this year down there

Whats everyone's performance as far as cruising speed, GPH with the 32 and twin 350 horizons? I took my trip from storage marina to my weekend marina on Fri. Weather was perfect with very little chop, light wind. I was at 3100rpm doing about 16 nts on plane and burning 21gph. Does that sound about right?

 

[BAC.94]

Can anyone direct me to fuel sender replacements for my 2003? Parts list info for port and stbd is:

Thanks for the help!

V-drives, here are my numbers from a recent trip. Not sure I van get on a on plane at 3100, I usually cruise at 3800. I would be right at 1mpg if my freakin port engine was as good as my starboard!
26mph/22.5kts, at 28.5 gph, this was a smooth, calm day, not sure about the current...

I’ll try 3600 next time it’s smooth...

That doesn't sound right to me. I have the 05 320 with 350 mags v drive and similar to Todd there is no way I could plane at 3100 rpm. I added the drop fins on my tabs and can now get down to maybe 3600 and stay nicely trimmed on plane. Do you have a gen set at the aft end of the engine room? Might not be an efficient speed for you boat, you may be plowing water a bit. I would try 3600 bottom up to 3800. See what your speed / consumption is. I'm easily 21+ @ no more than 25gph ever at that speed rpm combo. Generally never less than 1/2 gas

Hi Todd,

Where do you see that Fuel Page? I have upgraded to VV703 from the SC5000 but haven’t seen a screen like that. Is that Vessel View Mobile?
Thanks.

 

[Todd320]

Hi Todd,

Where do you see that Fuel Page? I have upgraded to VV703 from the SC5000 but haven’t seen a screen like that. Is that Vessel View Mobile?
Thanks.

Yes, VVM, it allows you to customize 3 pages, and that’s one of the ones I chose.
Now if I could figure out why my fuel burn is so much higher in the port engine. Tech is really experienced, we talked about like 5 things it could be. I wonder what the most likely is, bad injector(s)?
The image is a screen shot from a video, I screen record my fuel burn numbers every now and then, did a wot run as well, and the port engine only goes about 300 rpm less (4600 to 4900, if I recall...)

I added fuel burn to my VV703 screen last week and saw that my STBD engine was burning 17 GPH and Port 15 heading out and coming back STBD 19 and Port 15.2. I spoke to me mechanic and he said that no two engines burn at the same rate and a lot has to do with trim and sea conditions. I had the the boat trimmed out and and you can see by my rudder indicator at the bottom of my screen that my wheel was turned and I was going straight so what he said made sense. I ran the boat this past Saturday paying attention to how I used the trim tabs and my fuel burn was within about 0.5 GPH from STBD to Port with STBD always higher. My mechanic also said because the v-drives turn in opposite directions has some effect on fuel burn. My WOT is within 80 RPM’s of each other. Could be your props need tuning. All my numbers are based on my 8.1’s. Hope it helps.
