Official 370 Venture thread

[Whatta Life]

someone recommended not doing the gen software update . can someone tell me what the issue is with the gen ? Also is the house battery the same as the port engine battery ? looks like there are 2 for the bow thruster and one for each engine and that the house is connected to one of the engine batteries .

so we have agreed on price and terms , looks like this deal is going to happen . I really like this boat . I'm a performance guy , everything i own has been modified and so will this boat . Here are a few things i have planned . First , i'm in the Lithium battery business , so this boat, like my other, will be getting a set of custom built lithium batteries . I have to decide how i want to build them . Option one would have the same useable capacity as the boat currently has . Option 2 would have 3x the house capacity . This would be if i decide to install a huge inverter . Probably start with the smaller pack and then increase if i go the inverter route . Battery pack will 200lbs lighter than what is in there .

Second thing is a reflash of the verado's . This is a popular thing here in florida . Increasing torque in the 3500-4500 range . This will make the boat get on plane much faster . Top speed will be faster but i wont use it . 40mph is fine for me .

Third , new props . Going with more blade surface area . This boat has high prop slip , part of that is to make up for lower hp . With the increased hp should be able to go up 1" of pitch . Combined with the lower slip ,rpm's at 31mph should drop from 5,000 rpms to 4500 . Or at the same rpm cruise at 36mph . The newer props also have vents in them which make getting on plane even easier .

That will get me started . Open for any improvements others have done and recommend .

How does the horsepower of the reflashed engines compare to the manufacturer's spec for maximum HP for the hull?

 

[Whatta Life]

my understanding is that only boats under 20 ft. have a plaque with maximum Hp allowed . Doesn't apply to boats over 20 ft.

Don't engineers have design parameters they work with when calculating the forces a hull will be subjected to when designing a hull?

 

[Whatta Life]

Of course they do . What i'm doing here is having that power come on sooner . wont be an issue at all . Here in Florida we do a lot of repowers . In most cases people increase power when they put on new engines . Rarely an issue if done by experienced people .

I had it done without any issues. It took 45 min in total. The guy came on, removed the hush cover, plugged in a USB stick , ran it to look at vitals, and then that was it. I have put another 10 hours on it since without any issues.

I didn't do anything performance related, but if you want to chat before pulling the trigger on weird things to look for on your inspection. PM me and we can sync up.

Wondering if any 370 Venture owner has had this problem ... water (rain) leak unto the bedroom ceiling panels. Two panels must be replaced. They are thin plywood covered with vinyl.

Have not confirmed the source yet.

Any comments or thoughts?

Hey, did you by chance see any of my previous posts in this thread about the water intrusion I had? I actually noticed some exactly where you pictured as well. I resealed the helm cubby and the starboard lower windshield side glass and arch. Never saw it again. Do you let the boat get rained on? Do you cover the helm seats?

I have a 2013 and so far so good. fingers crossed!!!

 

[Whatta Life]

Picking up the venture tomorrow! Hope i can sleep tonight
Thanks Thebigb for the phone call today . Nice info to get me jump started and things to look for .
The list of upgrades keeps getting longer . Don't think i will be getting much office work done the next few weeks .
i have benefited from the knowledge on this forum , hope to contribute a bunch back to this group .

 

[Escape Cay II]

Thank you TheBigb! I will look at your older posts.

The two panels I removed will definitely need replacement. They are terribly molded on the upper side. Will post pics. Found the leak on that side to probably be a apparently useless screw through the fiberglass located just below the cockpit refer. Plan to reseal that hole with silicone caulking. The panel on the port side seems slightly warped, but haven’t pulled it yet to inspect. I’m going to add some photos. The vinyl panel covering material is available to order vis SeaRay.

I would love to share other problems and solutions. Let me know if this forum is the best/fastest way to do that?

Wow, crazy, that water must have been seeping in for a while. Did you just never notice it or was it hiding the whole time? So where exactly did you find that hole with no screw?

It had a screw in it and was leaking around the screw. I think leak was intensified after Hurricane Michael maybe. There wasn't much warping of the panels until recently. The screw looks like random thing. Held nothing down. Rain water apparently was coming in around the canvas on the starboard side and going down to the console where the cockpit sink/bar, grill and refer are located. My plan is to plug the hole where the screw was with silicone caulk, then check for more leaks.

Where were your leaks?

Here's another photo

Very helpful. You know that's sloppy of Sea Ray, and like i mentioned earlier i found screw holes with loose screws in them that served no purpose at all. The one that was letting water into the aft on mine was by the port side glass... just a drilled hole with no purpose at all and they didn't even fiberglass over it. I put a ton of caulk in it to fix that leak.

As for your picture, is that right below the helm seat bolts? I noticed they don't caulk or seal those either. When it rains i also get a water path behind the cockpit stove/grill. I found for me that after i sealed the side glass/arch and helm cubby it went away.

The last picture is a little skewed, but looking to starboard and that cabin window (port) is directly below. The crew was coming from inside the area where the cockpit refrigerator is located (2nd posted picture) that hole had the screw in it that just penetrated the fiberglass the crew wasn't removed in the last picture.

I will check for more leak potential points before I go rebuild the ceiling panels. I have seen some of the screws holding down the bar and grill in the cockpit were caulked. One of the ducts for the cockpit ac was literally full of water. (the one inside the wet bar) The two ceiling panels I have pulled off were so covered with mold, I'm concerned that the others will be too. It's obvious that this has been going on a long time? It seems that hurricane Michael rains did a lot of wetting the inside. Or max winds here in Destin were only 47 mph according to my weather station.

Maybe replace the plywood with something synthetic so that it wont retain water ?

 

[Whatta Life]

Here it is . One hour boat ride home , went well . Wife and kids love it so that's good . The Venture is actually smaller than my center console behind it but it looks so much bigger . Moving the cc to another lift in the next few days so the Venture will go on this lift . Realized my first problem , it has a hard bottom paint .
When out of the water for an extended period it will loose it's effectiveness . Have to figure this one out .
