Top speed of a 1992 with the mercruiser 4cyl?-gctid399914

[Guest]

Can anyone tell me the top speed of a 1992 bayliner classic 1952? (small cuddy)

it has the 470 mercruiser I/O & matching outdrive.

it is 18.8 feet long.

best estimate is fine.

as what I can find is saying anywhere from 20 - 28 knots, is this correct?

as always any/all assistance is greatly appreciated.

I get about 38-40 mph by speedometer on my 1952 with the smaller 3.0 liter four, with about 3/4 of a full load at 5000 ft elevation. I haven't checked that with GPS yet, so perhaps take it with a grain of salt. I'd guess you should be able to hit 35 mph (30 kts) with any luck.

I also get about 38 as per the speedo with my 1992 Classic with a 3.0L nthego:

thank you both for the info!! will have to check it with the GPS on flat seas and WOT :arr

this gives me a good place to start / know what to expect so I dont launch my arse off the boat going WOT LOL

is it worth it to go to the stainless steel prop?

[Guest]

I got 39.8 mph on my 1993 1952 with Mercruiser 3.0 4cyl. (1-2 people, no bimini, sea level)

And cruising at 28 to 32 mph I would get about 4.5 mpg.

Very good little, fuel efficient boats.

I miss that economy.

My 2252 with 5.7 v8 gets 1.5 mpg.

And on the stainless prop, I would say no.

They are pretty and sexy when they are polished and flex less, so I think they would be best suited for high horsepower speed boats where you don't want to lose a mph or two due to prop flex.

Also, if you hit something with a stainless prop, it is much stronger than an aluminum one, so it is less likely to flex, bend, or break when trying to absorb/deflect the impact.

That is not a good thing because then something else in your drivetrain will have to absorb that impact/force.

And that would be your outdrive.

Outdrives cost $1600 and up (aftermarket SEI) and cost at least $600 to be installed.

I agree 100%!

I am going from a 1952 to a 2455 and I too will miss the fuel economy, but will like the extra room! I am hoping it's a good trade off lol

[Guest]

thank you all for the information !

I greatly appreciate it

it seems this boat should be great fun while I work on my 1979 project.

the more i lean about the 1952 the more i like it

again thank you all and happy boating!!

took out the little 1952 bayliner classic today on the river to give her a good test run, 4 of us in the boat, estimated weight of people and stuff about 1000 pounds and we got the boat up to 30 mph by the gps. great fun!

I have a 1992 Bayliner 1851CB cuddy

I have a 185HP 3.8L V6 in it which has the same power as the HO 470 with the 4 barrel.

I can hit 47 mph with an aluminum prop, and 50mph with a stainless, but thats with 1 or 2 adults -

have never hauled 4 adults + 1000 pounds of gear.

[Guest]

sorry, not 4 adults and 1000 pounds of gear, 4 adults + gear total for everything about 1000 pounds.
