Looking at 180 Shabah 4.3L

thinkingaboutit · 04-30-2009, 06:24 PM

I am looking at purchasing a 180 shabah 4.3 and want to know how fast I can expect it to go? We want a boat that goes at least 43+ mph. Your input would be greatly appreciated.

Welcome to the board!

According to the brochures, a 180 Shabah with the 4.3 should be running in the range of 46-51mph.

(Assuming you meant MPH instead of MPG) Not sure what your Gallons Per Hour fuel consumption rate is, but with it being a fast hull, low weight, and adequately powered engine, I'd assume it gets pretty good mileage too.

But there's a lot of 180 Shabah owners on here, I'm sure you'll get a lot of great testimonials.

I can top out at 50 mph. As far as mpg not so good. When I run the 4.3 at a good clip it hurts the good old pocket book. But its just money. Time on the mariah priceless.

Depends on what prop is on the boat but if it has a standard 21" pitch 3 blade aluminum it should hit 50-51mph. With a 19" pitch prop (gives better low/mid range grunt) it should top out around 46-47mph.

They're a good solid well built boat and if well maintained will last a long time.

I just bought a 1998 180 4.3 with 50 hours on it. I'm in the middle of trying different props now. Monday was a 14.5 x 18 pitch 4 blade. topped out at 41mph 4400 rpm. Today I put my original 14.5 x 19 pitch 3 blade back on. topped out at 44mph 4400rpm. people are tell me to go to a 21 pitch stainless 3 blade should hit 50mph. I am going to have a couple different props, 1 for speed, 1 for pulling the kids on tubes, and one better prop. Love the boat. Today was a 1' chop on lake michigan (Escanaba) the boat handled like a dream. first time boat owner but I've been in alot of different boat, but nothing like this one. cuts through the water like a hot knife through butter. Very smooooooth. Sorry for getting carried away, can you tell I like my newused boat. Hope this helps

My Talari 180 has a 4.3 with a stainless 19 pitch three blade and it will do 53 mph with my wife and kids on board. My RPM is right at the limit of 4800. If you go up in pitch you can expect about a 400 rpm loss per inch of pitch. We live at 1200 ft elevation. If you get the boat post some pics so we can see it.

Mikey's advice is right on.
My 1995 Talari 180 has a 19in Stilletto and my brother-in-law's 1994 Barchetta 180 had a 21in Stilletto.

My top end is around 4900 rpm and around 47 to 48 mph. My brother-in-law could get to 52mph, not sure of the rpm.

I prefer the acceleration of the 19 as I can't afford to run full throttle. Also, the engine doesn't have to work as hard with the 19.

Propnut,

Pretty impressive results, 53mph @ 4800 rpm.

What brand prop are you running?
