Boat accelerate from 0 to WOT (Bayliner 175)

why all the comments for 30 sec clip?

i want to see an SR20DET in one of these. now that would be fast. or even faster and cheaper but much more noisy, KA24DET.

I pay about 75 bucks for a full tank in my boat.

[jaguarnumber9]

My boat gets good gas milage for its size. But then again we do run the hell out of her. Its not to expensive for gas. It has a 30 gallon tank,

[mooseling1]

@jaguarnumber9 How much is a gallon of gas where you live? in the UK you are looking at around 9 or so dollars per gallon... So a 30 gallon tank is 270 dollars. We may not be using the same size of gallon but i am sure it is roughly similar... I am taking a gallon to be 4.5 litres.

I see my Captiva has always been fresh water. She has not upgrades. The water in lake Powell is very rough in the channel so you need a boat that can take on some waves. The bow rider design is over all great.

[mooseling1]

It is very sheltered in the channel so even in the biggest winds the boat will get you back safe, if not quite wet from the spray, and when driven properly it wont slam in waves and the ride wont be punishing. I have been travelling faster through waves in my 5.5m GRP planing boat than 6 metre ribs, its all in the way you drive ;) back at the marina the person in a rib i overtook in big waves asked how i got my RCD C boat going smoother than his RCD B rib. But 6 miles south waves get up to 4-5m

[jaguarnumber9]

I get what you are saying. I run my Captiva on lake Powell which is huge and so i run her WOT Alot. I just think the prop gives my boat Alot more versatile use.

@jaguarnumber9 I run my boat in scotland, off the west coast. The area is wonderful for boating, especially in a fast boat. The marina i keep the boat in is ten miles from another marina, 12 miles in a slighlty different direction from another marina and 9 miles from a city on an island which has a some pontoons so you can stop there. And the channel is well sheltered by an island only 2 or so miles away from the marina and tall hills on other side. The island has a small pontoon as well.

@jaguarnumber9 Sorry about some random info there, but at 30 mph you only need 20 minutes to get anywhere, and about 3 minutes to cross the channel. And if you live in the USA then you dont need to worry about efficeny. In the UK a boat doing 6 mpg costs 16 pounds of fuel for a 20 mile round trip, changing the prop would take that up to around 22 or 23 pounds. 7 pounds isnt a lot, but think of it. Over a year that takes the fuel bill up 350 pounds, or 630 dollars (i think) with no advantage

O i c. I have a rinker captiva 192 and it has a 4.3liter mpi thunderbolt engine and from a standing stop i put her wot and she comes out of the water and on plain in seconds. I also have a mercruiser alpha one but i have a high five blade stainless prop!

[mooseling1]

I have tried that before, and get a 0 to 30 mph time of 6 seconds (with one or two people and literally only 10 litres of fuel, and no significant weight on it) in flat calm seas. And it is fast considering it is a boat. A while ago the propeller got a dent on one of the blades so i was in a position to look at getting a new prop. I fixed the old one as well (took it to a mercruiser dealer) and was going to get a 4 blade prop. but decided not to due to lower efficiency and i am happy with 3 atm

[jaguarnumber9]

@mooseling1 Yea my five blade makes a tremendous difference in the boats overall performance. I did a top speed at 40 MPH with a standard 3 blade aluminium and with my five stainless it did 55 MPH.

[mooseling1]

@jaguarnumber9 I rarely cruise at full throttle, i spend nearly all my time at a comfortable 30 or so mph which gives around 5-6 mpg. Fitting a 4 or 5 blade prop would have increased top speed to over 50 mph but the efficency of the engine would have dropped and for the one time a year i stay at WOT apart from accelerating i didnt think it was worth it.

[jaguarnumber9]

Thats cool did you have her wot the hole vid?? cause if not u need to open up the exauhast tabs on the prop.

[mooseling1]

@jaguarnumber9 No i accelerated slowly up to about 2000 rpm, then at 8 seconds i pushed the throttle to about 90-95%. It is to avoid going straight from idle or a low RPM of around 800 to full throttle. Also this way you take the boat up to the point just before planing and then the power takes it staight onto plane rather than slowly climbing up onto it. You actually feel the boat surge forward at around 8 seconds.

[jaguarnumber9]

what kind of mercruiser motor is in it

[mooseling1]

@jaguarnumber9 A petrol mercruiser 3 litre 4 cylinder engine with 135 hp, rev limit at 4900 RMP. Connected to a mercruiser alpha 1 sterndrive with standard 3 blade propellor.
