2120 Parker Repower Cost

[mrfunandson]

What’s the top end and cruising speed for the Parker 2120 with a Suzuki 200?

35 - 36 knots (roughly 40 miles an hour). compared to the original 150 when she’s up she really wants to run

I have a 2110 that I just repowered with a Suzuki 200. I am still going through the break in period. I haven’t ran it full throttle yet but at 5000 for a short time it was going 35mph. Feels like a different boat.

What prop do you have?

a 15x17 3 blade prop should get you to 42mph @6k RPM and cruise 25-28mph @ 4200-4500

At least that's what I was getting on a 200hp Yamaha 4s.

My prop is a 3 blade 15x21.

My prop is a 3 blade 15x21.

your motor should be running @6k RPM WOT, depending on where you boat and what you do, you may want to drop the pitch down to 17. I bet your hole shot isn't that great with that prop and you're probably having a harder time to get the bow down. That motor I believe is a almost 100lbs lighter than my 200 yami so you will have an advantage though

My current prop is 14.25x15P 4 blade and have only get up to 5600 RPM. I have not been in calm enough water to give it time to climb and my loads are generally pretty heavy, 4 guys, ice, gears that's before loading up with a couple coolers of fish.

Boat runs great. I have a much better hole shot than my 150 hpdi with a 15p. It is a new boat with the repower. The Suzuki has a bigger gear box than the yammi allowing for the taller pitched prop.

2003 Standard notched transom... anyone have the control cable/rigging length? Putting on a Suzuki DF200

I have the digital controls with my Suzuki 200. Keep us posted on how the boat performs.

 

[2801 Parker]

Having repowered my '03 2801 CC with Suzukis: If I had to do it again, I would not consider another brand motor. They have performed outstanding (1300 hrs). Timing chain, not a belt that has to be adjusted at 700 hrs (yamaha). Parts to do your own servicing are less expensive than yamaha. Turns a bigger prop. quieter than yamaha, etc., etc....

Now, with that said, anyone buying a Parker that is prior to '05 needs to be concerned about the fuel tank(s). Failure of the fuel tanks are common with the Parkers and the only way to replace them is cutting the deck. There is much info out there on this. I am currently replacing my 150 gal. tanks which requires removal of the console, and seat/livewell, in addition to cutting the deck.

I repowered my 1988 23SE with a new Suzuki 175 with a 16X18.5 prop two years ago. In my opinion this engine is plenty of power for my boat. I jumps onto plane with no effort in what seems like about 3 seconds. I usually cruise at 3500 to 4000 rpm, 3500 rpm is just over 20mph and 4000 is 25mph. Max rpm with my prop is 5400 and speed is 35mph. Very happy with this motor and the boat's performance. Going with a 175 vs 200 saved about $2000. Knowledgeable dealer said there is no difference in 175 vs 200 until you exceed 4000 rpm. Lets face it, in anything other than very calm conditions the Parker SE's can't be run comfortably at much over 15 knots.

What kind of miles per gallon do you guys figure you are getting with your boats? At 1000 rpms I go about 5 mph and get about 8 mpg. At 3500 rpm I go about 20 mpg and 4 mpg. 4000 rpm is 25 mph and 3.3 mpg.

Suzuki seems to be sweeping in all over Chesapeake Bay. I see it on repowers and new boats. Only complaint after 500 hours with my 2016 Yamaha 2000 on my 23SE was the banging from prop gear lash at 600 -800 rpms which was solved by changing from stainless to an aluminum 14.5x17 prop. With two to four people and a full tank planing is easy especially using the trim tabs. In light seas, 3400 rpm makes about 23MPH and uses 4.3 MPG. 3600 makes 25 and 4.0 mph and 3800 pushes the speed to 28 and drops the mileage to 3.8. Max speed is about 41 at 5400.

Hey John,

Do you mean prop banging at 600 to 600 rpm. I had the same issue with another boat with a Suzuki 90 hp with a stainless prop. I switched to aluminum and it did not make prop chatter noise at idle any more so I stayed with aluminum.

It looks like your speed and miles per gallon numbers are better than my Suzuki. I think my prop is probably not optimal for speed and mpg. Maybe my prop has some other attributes that are not readily measured, I don't know. Another guy I know repowered his 21SE with a Suzuki 200 and the dealer gave him a 15.25 by 19 prop but I don't know what his numbers are.
