Official 370 Venture thread

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 .


I've changed out my props and it was the smartest decision I've made. Check out my earlier posts on more information.
 
Hey guys, has anyone considered a front bimini? I've been doing this 4-6 hour trips in Florida and its freken hot at the helm!
yep. just depends where sun is at and your direction of travel. my smaller center console provides more shade for sure.
 
I would like to poll Venture owners to see what props they have on their boat now. I have 4 blades. I have no idea what diameter and pitch since there re no markings or numbers on the props. (I am not original owner.). I know that it came from Sea Ray with 3 blade props. When I look at pictures of Ventures for sale on boat trader, I see only 3 blade props.
 
Hey All,

Wanted to post an update, it's been over a year with this boat. We live in SW Florida and use her 365 days a year. We keep her in the water and during the summer she is scraped every month and during the winter every 2-3 months.

No major issues. Had a fuel censor replaced and some other small things. I noticed if I run her at least once a week, everything continues to work smoothly.

I talked about it in my earlier posts, but my major issue is the boats ability to plane with 5+ people and a full tank of gas. With the tabs all the way down, I would have to ask people to move closer to the bow to plane. I'm not the only owner who complained about it and I think this boats lack of power is why it was discontinued.

Mind you, the boat is plenty powerful and I'm easily one of the fastest large boats on the water at any given time. Once Im on plane, 35mph+ no problem. The issue is you need to hit 5300 rpm to plane and the boat just seems not able to get over the hump.

I looked into more power but the boat isn't rated for it, no one would do it.

Which left me with the props. A few mechanic friends told me to try different props. MarineMax argued with me constantly, probably because they were trying to sell me a different boat.

My 370 VN had the 15.25x147 Mercury Enertia Propellers on her – these are the props spec’ed per Sea Ray.

PROP, SS 15.3 X 14 RH ENERTIA
PROP, SS 15.25"X 14"LH ENERTIA

This is what MarineMax told me:
The only possible option I can find at this time is the Revolution 4 - these are four blade performance propellers from Mercury Marine. The smallest pitch offered is 15” - you are running 14” three blades now. In all likelihood you will lose some WOT RPM, possible even make the on plane performance worse. Will not know exact performance unless they are installed and performance test are run.
I do not have a set that we could borrow to test. If we order and test a new set they cannot be returned. Once a propeller goes in the water it cannot be returned.

I told them I wanted the new propellers, please order it and install for me.

They said:

In order to possibly improve on plane performance smaller pitch propellers can be installed – however, there will be an adverse effect on midrange and top speeds, and a possibility of engine over rev as these propellers will actually be too small a pitch.
Sea Ray and Mercury do extensive testing to ensure they match the most efficient propellers to each engine/boat package.
Per Sea Ray & Mercury (I also believe) the best all-around propellers are the ones now installed on your boat. We can sell you a new set of smaller propellers to try, however I cannot guarantee any measurable improvement.

It took 4 months on backorder but I finally got them. I had my diver install them himself as MarineMax was going to charge me to pull the boat out of the water.

My new props:

48-8M0070074
48-8M0070076

I'm SO HAPPY I made this decision. The boat loses some top speed, maybe 3-4 mph when running full throttle but I get on plane in 1-2 seconds versus 30 seconds. She's got a lot more torque and grab. When running at low speeds I also notice handling is much better.
 
SatoshiVenture ...

I think I must have the 4 blade Revolution props you mention in your post, although I haven't been able to locate markings to assure me that's what I have. using the part numbers you indicated you installed (48-8M0070076 & 4) they are Enertia 15.6 x 13. 3 blade. Am I correct?
 
I am told the Enertia 14 pitch are the OEM props. I have Revolution4 props ... 4 blade with 15 pitch The previous owner swapped props. I’m either going back to factory or going to the one SatoshiVenture is running.

gotcha. I have the OEM 3-blades. I would like better acceleration (currently diificult to plane) and planing at lower speeds.
 
Hey everyone. I went to turn on the under swim platform lights on and nothing? The switch lights up but no lights. Is there a breaker or inline fuse somewhere?
 
Probably, check master 12v panel below captains seat. Then check bulbs ... which means out of the water though


I did check the panel and there's nothing there for it... Doubt it would be both bulbs at the same time. I can't determine which wires down below actually go to the lights
