Default Parker 2520 Repower and update :Motor Installed First Run

Just purchased a 1999 Parker 2520 Sport Cabin MV. Has a 200 yamaha saltwater series II mounted on the transom. Found it pop up on craigslist one evening and went and bought it the next morning. Was well maintained by a marina and was used on a few trips this year. The prior owner went to start it up for their most recent trip and could not get it to turn over. They could only get the flywheel to turn a few inches either way by hand.

So first item to be addressed will be the motor. Looking for any and all advice on this part. As of now I am planning to repower with a good used motor of the same era, ideally a 225 or 250 ox66. I have also been thinking about a mechanical yamaha 4 stroke such as a F225 or F250 as I should be able to save all the rigging except the tachometer.

Electronics,lights,tackle station,interior update, fresh water tank and more will follow once I get it back in the water and make sure everything else checks out. I have done lots of glass work and boat repair/building so not afraid to cut into it a bit

Would also love to close in the transom and put a bracket on but that is a project for the winter time.

I will be getting more pictures when I am back down at the boat as it is currently two hours away from me.

I am in year 13 with a Parker 2520 Mod-V with a Yamaha F225. I love the boat so much that I donít think I could bring myself to sell it, itís become almost like a family pet. That being said, itís no speed demon with the F225. My boat runs heavy all the time with a lot of anchoring tackle and often dive gear, so take that into consideration but STILL the 2520 is a lot of boat to push with the F225. My engine has been great, 1700 hours and still kicking but it works itís ass off. I am propped so that I can get 5700 rpm with full fuel and a fishing or dive load but top end is only 28kts. This being said, while underpowered, the boat is extremely economical in terms of fuel burn. There is IMO a tendency to over prop the 2520. There is a huge difference in the way the boat performs with 1/2 a gas tank and 1-2 people compared to full gas, in the case of my boat thatís 150 gallons of fuel and LOTs of heavy gear.


IMO if you are going through the trouble and expense of a repower, I would not even consider an engine less then 250HP. When repower times comes for me itís still up for debate if it will be Yamaha or Suzuki but one thing I KNOW for sure is the engine will have 300 on it.

Best of luck with the boat. Yes, some of the bad ride characteristics of the Parker 2520 Mod-V guys love to write about on THT are true but learn to use your trim tabs and accept that in certain conditions 12-14kts is gonna be about it unless you want to pound.

Iíve run my boat April-November in New England, through all kinds of weather, boat is a 2005 and doesnít look new, but IMO it has held up remarkably well to a lot of hard use.....

I would love to put a 300 on it and that is ideal power but unless I find a good deal on a setup with rigging I am trying to find something that would just be a bolt up replacement and get it back in the water. After this season I would start looking at new repower options especially if I close in the transom and throw a bracket on.

Thought I had a motor found for the boat but it fell through.

Does anyone know what motors are compatible with the controls that are currently on the boat if I were to switch it over to 4 stroke power?

I'm don't know which controls you are running, but the Yamaha 703 control box on my 2014 F90 Yamaha 4-stroke was originally used on a 2000 F70 2-stroke.

If thats an original motor you might want to get new everything.

The problem with the 250’s is they haven’t been out long in mechanical version. The 4.2 block.

Finding a used one one at a good price wouldn’t be easy. New 250 or 300 aren’t cheap. The 300 doesn’t cost much more. I believe the mechanical 300 hasn’t been out as long as the 250.

The 250 4.2 block would do fine on that boat.

I ran one with the old 2 stroke 225 Zuke with 2 plugs per cyclinder. It would move pretty good

Very rarely could I even run the boat that fast without getting beat to death. Mid 20’s was ok. Over 30 it had to be pretty calm.

Its a rough riding boat. Have to slow down and use tabs.

I have many hours on a 23,25 DV and MV and the 28 DV.

The DV rides way better.

The boat is tough and built well. Just not a great ride.

Just have to slow down and learn how she rides.

As of now the plan is just to get the boat back on the water for the rest of the season. Then over the winter may go with newer power and close up the transom.
I am mainly looking for a Yamaha f225 to repower the original 2 stroke with. It may be a tad under-powered but I do not need to be running the boat fast anyways. If I could find a nice 225 or 250 ox66 I would jump on it as well.
From what I have read the controls should be the same between the older 200 and a 2003-2005 f225 except for possibly the gauges.

You talking the the mid 2000’s 225 4 stroke ? If so look for corrosion issues.

A 225 2 stroke will be ok. Just prop it right.

Just expect low MPG’s.

Use to fish 40 miles offshore all the time in one.

Burn 70 gallons going around 100 miles total.

Pretty good fishing load. Cruising 25 mph’s.

Not really apples to apples, but I used to have a 91' 2510 DV. It came with twin 2 stroke 150's and I updated it with F150's (4 strokes). It sat much lower in the water because of the added weight, even though I had an armstrong engine bracket. It still needed more float. It also wasn't a speed deamon, even with 300 hp. I used it to fish offshore so I frequently had full tanks and 4 people.

So even though it isn't an exact match, lessons learned were to check the relative weights of old and new power; 4 strokes are heavier and bigger is also heavier. You may need a bracket or upgrade. Also, don't skimp on hp if you can afford it.

And yes, if you get a new engine you will want new controls. Fuel management, connection to your electronics, etc.

Have a few updates on the boat and motor.
I had the boat hauled out and blocked at a local marina in little egg harbor that has been great to work with (munroes marina).
I sold the original yamaha 200 saltwater series 2 and have a newer yamaha f225 four stroke that will be hung later in the week, and I am aware that it is a weak 225 and they have the midsection issues. All I wanted was something reliable and will aid in resale of the boat if I decide to sell and go with a center console.
While I believe all the rigging will be the same I did buy the new motor with all rigging and gauges.

Once the motor is mounted I will do a "shakedown" cruise when I run the boat roughly 40 miles from Little Egg Harbor to Brielle where it will be kept.

If all goes well I will start putting the list together of other upgrades.

Glad you found your motor. I was going to help and say the motors are usually on the stern (square end) of the boat.

I have the same boat, right down to the same year. Bought it new with an OX66 225 hp Yammie. Still going strong with 1300+- hours. Tops out mid to upper 30's MPH with a clean bottom and half a tank of fuel. Congrats.

Went down to Little Egg Harbor yesterday morning around 11am and started to swap over any of the rigging that needed to be changed. Everything control and gauge wise was the same from the original saltwater series 2 yamaha to the f225 yamaha. I started by removing the oil tank from the old 2 stroke, Only thing I needed to change was the battery cables and I put all the cables into a 2 inch rigging tube as they were all open originally. Also put some new fuel line in and moved the primer bulb into the transom storage box.
Once everything was hooked up I pulled out all the plugs and cranked it to make sure no oil had gotten into the cylinders as I had the motor somewhat sideways for transportation. Decided to put new plugs in as well since they were all coming out anyways. Primed the bulb and it fired right up.
Due to the low tide down in Little Egg we ended up having to wait a little over an hour to put the boat in the water so we decided to trailer it over to the Wawa up the street and top it off with fuel.

Ended up leaving Little Egg just before 7 and made a 56 mile run out of little egg inlet up to Manasquan inlet. Got to Manasquan around 8:40 and tied up at the fuel dock to go check out the slip. Ended up not getting everything set up until around 10pm and still had to go pick up my truck from Little Egg.

Could not be happier with the way the boat ran especially for it having the Mod V bottom.

Will be bringing down the actual dock lines and cleaning the boat over the weekend. Very glad the original spreader lights worked along with the nav lights.
