View Full Version : opening up a 190

09-28-2004, 04:02 PM
has anyone ever heard of a prostar 190 having the bow opened up.
was just sitting at work with nothing to do and thought that it would be a pretty original look, but very complicated to do. Could look pretty cool if it was done right but it might throw the balance off a little.

Never crossed my mind. This should be an interesting thread. I'll stay close to this one. Great Question! :rolleyes:

Someone with a 190 want to barrow a sawzall.

Interesting concept. I guess it would look a lot like a Malibu response with the walk over windshield. I don't think there would be much room other than enough space for a two person bench. (like the Response) It might be tough to step over the windshield as the PS 190 is a solid windshield in the center. I too would love to see some pics.

If you go on MBO site,one of the regular there just finish his conversion on his Malibu.
There's picture of it before and after.Great job!
I think he kept the cutout piece to make some kind of cover...
Very courageous...

Andre, you beat me to it. Those Malibu guys have full-photo'd how-to's about converting closed bow responses to open bow walkovers. My two cents is that it'd mess up your awesome closed bow storage. That being said, I'd love to see somebody give it a whirl.

09-28-2004, 05:51 PM
How about a link to it, guys?

The site appears to be down at the moment. I'll update this later. But for the time being, www.malibuboatowners.com

Check the "how to" section. I don't remember seeing it last time I was there. If you don't find it, try a search for "open bow conversion."

09-28-2004, 06:01 PM
Did both. Have to register to do a search. And didn't see it in the How-tos at all.

09-28-2004, 06:03 PM
Hope this work...

God,I'm really a computer wizard!!!

09-28-2004, 06:20 PM
Thats it, thanks Andre'.

Looks nice, but then I'm the kind of boat owner who doesn't store a ton of things in the boat & doesn't care if it ruins the "pure ski" aspect of the boat. I have a naugahyde tonneau on my bow & we store a ton under it while we're out. I have thought of making a fiberglass tonneau for it similar to the one on my Dodge pickup bed.

09-28-2004, 06:28 PM
The dude did a nice job. That said, I wonder if I could close my bow:uglyhamme

09-28-2004, 07:33 PM
I wonder who will sit up there?
Sorry guys, I liked the boat better before the conversion.
I'm sure it's still awesome to ski behind though! ;)

09-28-2004, 07:55 PM
The same people that sit up there in any other bow rider. No shortage of takers in my boat.

09-28-2004, 08:01 PM
Air, nothing against open bows, there just doesn't seem like much space with that conversion. Your boat was designed for open bow.

09-28-2004, 09:39 PM
I don't know if Malibu still makes all of their boats as closed bow and cut the ones that need to be open bow, but when I worked at a MC MB dealer, we cut a few of them to make them open bow and the nice padded insert for the opening and the seat cushion are Malibu parts. They just drop in and attach from underneath. It's not very hard to do the mod on a Malibu. If I'm not mistaken, they lay up the 'glass of the bow heavier around the outer parts and that makes it easier to do without having to beef it up. They also don't need a separate deck mold for the open bow models. It makes sense from a manufacturing point of view, but I think a walk-through is a lot better than having to step over the windshield. Safer, too.

On the other hand, the open bow MC boats have the 'glass behind the seats sitting on, and attached to the floor and the seats attached to it. This makes the whole bow area stiffer and, I think, more functional.

MarkP... don't cover yours - I'll switch you my 95 PS 190 with 740 hours for your 205 - even up :eek: . What do you say? :smile:

i have a 2002 190 with the bow opened up. it's called a prostar 197. they can do it straight from the factory!-tex

According to the MBO board, the mod took 10 hours and cost $900. The 197 factory conversion sounds a bit more expensive.

Here's another thought. Wouldn't it be nice if us 205 owners could buy a full observer seat with a hinged back for the walk through. I guess all that'd be required is a seat base from a 190. The hinged seat back could probably be fabricated. It would make it a little more difficult to get into my ski locker though. But a little sawing could turn that into a cooler pretty easily.

east texas-factory conversion more expensive? i am reminded of that once a month!

When I was younger and poorer I would do crazy stuff like this.. Why on Earth would I want to f up a boat like that..

How about now, Powerslot? Look any better? ;)

09-29-2004, 12:02 PM
much better....

MarkP - at least I tried! :D

Besides - I promised to sell my boat to someone else when I'm ready for an open-bow. I can't really p!ss off my engine builder, now can I?

09-29-2004, 04:02 PM
Don't do it !!! Don't do it !!! Malibu places a STENCIL then cuts out the open bow from a closed bow boat. Adds $2600 MSRP and calls it a open bow. The Prostar 190 vs the 197 is 2 totally different decks. We do not take shortcuts in the manufacturig process. DO NOT DO IT.

If I were to go shopping for a new boat today, I would give a 197 or 209 a good hard look, even thought I once said I will never own an open bow boat.

But a step over, open bow 190, no way!
As I said, it just doesn’t look right.....
Kind of like an open bow Porsche......

I've got a thread on the Malibu board searching for the step-by-step conversion. The original guy to post this in a gallery lost his gallery apparently due to the budgetary constraints of that privately run board. Somebody posted his handle in the thread. So if anyone's interested in seeing the pics, they could go to the 'bu board and send this guy a message. It's not Jason, it's another guy who originally posted it a while back.

As for the conversion, I could see it happening on a 190 and looking really good. But for the two-piece deck, I was under the impression that the 197 and the 190 were the same. I don't think a walkover would look so bad. Just my $.02.

09-29-2004, 06:27 PM
I've got a half of bottle of Jack and a 3 foot hole saw :eek: , anyone need assistance?

09-29-2004, 07:17 PM
For you guys in the colder regions, you could just use an ice auger, for that matter. I have seen some pretty interesting sculpture done with chain saws, too.

It may not look bad to open up a 190, but look at the dash and see what it will take to step over the windshield, especially on choppy water. The MB dash extends farther past the top rail of the windshield, so on that boat, it's easier to get into the front.

09-29-2004, 11:21 PM
My 190 is known for having waves slosh over the bow. What would happen if that was open? SWAMP! :friday:

09-29-2004, 11:50 PM
So, what's the bilge pump for, anyway?

09-30-2004, 05:50 AM
My main purpose would be so that the kids have a place to sit. So - I really don't care how hard it is to get up there :D

Very interesting project... but I have to say "you first" and not with my boat.

Haven't you ever heard of a kiddie pool? 8p

This has happened with my 205 once. Probably not telling you anything you don't already know, but apply power through oncoming wakes/waves. If they're too big and still come over the bow, find a lake that doesn't have waves on it.

If my old Tristar would of had a "playpen" type of open bow it would have been called a Ballast tank.. That thing took on so much water it would have been a submarine ....

When it happened to me, the water just ran into the ski locker, and through the drain from the locker to the bilge, and out through the drain hole later.
