1995 baja 236 ?
 

Does anyone own or have experience with a 95 baja 236? I purchased boat with a 496 mag and curious of what prop would be my best bet for all around performance and speed. Currently has a 21p mirage plus and not to happy with overall speed 45-50 mph. Boat has original bravo 1 drive that was originaly powered by a 454. 496 mag 375hp was installed and everything else left the same. In reading motor specs WOT should be around 4600-4800 rpm. Im able to go over that with 21P prop, looking for a prop that will keep me in that range with best performance and speed gain. Runs 30mph at 3500rpm currently. Im not sure of gear ration in bravo1 buts its original drive fron 1995. Any suggestions are greatly appreciated.

That is not a very common boat. I have a 94 and I have taken it from 55 to 70 MPH. When I had the 330HP I had a 21pitch Mirage prop it ran 55 MPH @ about 4700 RPM. Do you have a GPS? If you are turning 4600-4800 you should be in the 55 to 56 MPH range.

Yes it is uncommon but thats one of the reasons i like it. Im getting 50ish on gps but rpm's will climb up over 5000 and i have to back off throttle. Im afraid of gernading the engine by over reving due to to small of a prop. This past weekend i happened to look down at rpm gauge and it was reading up over 5300 rpm and climbing. I was also given a new michigan wheel apollo 23P (part#993026) with boat i have yet to try. Im sure it will help but is it enough? What was your stock bravo 1 gear ratio?

I was tied up next to a 25 Outlaw last weekend, there is so much more cocpit room in the 236 than any other power boat I have seen. I have had mine for 11 years and have kept it because of all the things that make it different. Like the walk through windshield with the molded in steps, anchor locker, ect... Getting back to your issues. The tach may be off. The 496 Mag has a rev limiter. Tap on the gage it will usually go back to normal. The Mirage prop works well on that boat, a lab finnish with "double cup" makes a big differenct. You should be able to run 4800 RPM @ 56-57MPH. You may have somthing out of wack with the engine. Start with the easy stuff like plugs, wires, timing, then let us know what you find out after that. Here is a link for you to play with. Your prop slip should be very low due to the deep propshaft. Mine is about 10-11% with the lab finished 25 Mirage. http://www.rbbi.com/folders/prop/propcalc.htm

Where do you live/boat at?

mirage prop work the best and give you top speed !!!! i try a lot of props the mirage ,not the plus.:boat: the plus runs 200 more rpms then the old mirage .rember one pitch is 200rpm. you need to no wot is on your motor and prop it closest to that number and your boat will run the best:party-smiley-020:

Are you sure your tack is accurate?

Thats what I am thinking. Mine wigs out every ones in a while. He has not replied back he may be waiting till he tries it out again. The numbers do not add up.

Im in new jersey and boat along Mullica river out to atlantic city usually.

What was your original gear ratio in 94 with a bravo 1?

Havent been able to get out on it recently do to work schedule and weather but will try again as soon as i can get out! Had an issue with oil temp rising at WOT but new pump should correct that next time out. Seems like im constantly working out the bugs since i purchased the boat.

Still running the 1.5 ratio with 500 Hrs.

have a 95 236 bought it new had a 300 hp brave 3 spinning
24 p at 4800 1.81 gear speed was 61mph now she runs 81
with 575 hp and 28p 1.81 try a brave 3

Bravo 3's are much slower than Bravo 1. Do you have a GPS? There is no way 300HP will get you 61MPH with any outdrive. A 300HP engine with a Bravo 3 in a 236 Baja = 53 MPH. Also no way you are running 81 with only 575 HP.

LoL ill be happy with a consistent 55mph with out my oil over heat alarm going off.

do have a gps and a radar gun dont think they are both broke
it does surpise alot of people how it runs. i have try a brave 1
on the boat with a 1.51 gear and it lost 5-7 mph.i was told that a brave 1 would be faster but it wasnt just my 2cents.
i know it works for me because i own the boat.

before i order the boat from GSC we did a test drive on a demo boat they had at the water show. it had a 300hp and a brave 1.51 boat ran 56mph i order mind with the brave 3. with the brave 3 the motor is a 350 at prop because the brave3 take a lot more power to spin and ran 61mph

OK, this is the first I heard about the oil alarm. Are you still running the stock oiling system from the 330? That system sucks, the oil cooler is the size of a beer can. Take a look for a thread called "Oil system problems with stock hardware" somthing close to that. I use a 3"x18" oil/ps cooler. I switched out all my lines and fittings to 12AN. With 375HP you may not need to go that big, a 2"x18" would probably be fine. AN fittings may not be required but at least get some non restrictive fittings. Hope that helps.

So you had a Mag engine not the 330HP at the crank engine. The Mag engine in that year should have been a carb 365HP at the crank. That would give you about 330 at the prop.

the 496 that replaced the 454 was complete meaning it was a complete bolt in. i think i have that issue figured out. Have two things to change one is the raw water pump its worn and not pumping enough volume of water (will not hold suction at idle on muffs). I have more water flowing out of starboard exhaust then port side, slowly heating up oil considering 496 oil cooler is located on port side. I have also noticed a new exhaust manifold that was put on port side is cast iron with original aluminum one on starboard side, causing different temps on each side of engine. I purchased boat last year shortly after the re-power was completed and seems im stuck working out the bugs!

Do you have any pics of your 236? We had a 95 also and it had the 454 with 300 hp but don't know what gears it had with the bravo 1 and I think it ran around 50 if I remember right. We ended up saleing ours to someone in New York and bought a 05 275. Here is a pic of our 236.

Your boat looks great.

I wish Baja would have kept putting the port hole windows in on the performance models. The only thing my wife didn't link about our was the ladder she and few others said it was hard getting back in with wet hands because there hands would slip back down on the curve part of the ladder.

A little grip tape and a heat gun fixed that! Had the same complaints. lol

Nice boats, I had a 96 236 with 7.4 300hp bravo1, would run 53on gps with 21 mirage. It was all stock, bought it new and put about 300 hours on lake erie and another 300 on the gulf of mexico after moving to florida. Got rid of it in 2002.

Ive been telling him that for years,,,, he doesnt listen to me either !!!!:evilb:

Its simple math, not worth arguing about. :lolhit:

Stuck,

Let's make that a fall project before you put the 275 in storage. I will order the port windows, and you bring the boat, and some beer to Bucyrus, and we can have them installed in 3-4 hours depending on how much beer you bring?

XT:drink:

XT sounds good but I'm not sure how good port holes would look on our boat with the paint scheme that's on our boat. The port holes would be in the orange and that might look odd. I think the paint schem on our boat has to be one of the better looking paint jobs out there but then again maybe it's just me since it's my boat so I'll just leave our boat as is but if I change my mind I know how to get a hold of.

That is true....I remember designing older paint jobs that did not interfear with the windows, then production complained that port windows were "too hard" to install, and sales deleted them even as an option, then the paint lines no longer mattered. At that time it seemed that production had more say than the customer, and I lost that battle.

XT :asskiss:

whos arguing i left this out when the 236 was order
the b3 gear ratio was 1:81 spinning 24s to 4800 rpm when the 600 hp was put in the drive was change to b3 2:00 gear with 28s the prop where work by mel riggs and top rpm
was 5800 rpm so do the math
p.s ask obnoxus who looked at the back of whos boat
and he was with me when we try the b1 and it was slow

I had a 272 with a 330 HP 454mpi !!!

I had better of been slower !!!!!!!
