Default Is 150 on a 202 Robalo explorer enough?

We found the boat that works for us this weekend. My friend with a 21 ft Contender is telling me a 150 yamaha isn't enough on the Robalo. The extra cost would put it over budget.

Define ‘enough’
I have a 21.5 ft Seaswirl Striper 2101 WA with a 150 - so a bit more boat and the extra weight of a cabin. It’s ‘enough’ to hop on the plane pretty quick with 6 onboard and with 1 or 2 onboard can just about hit 40 when everything is in its favour.
Yes it would be a lot nicer with it’s max of 225 (one day!) but 150 is enough, even allowing for the Yam not to perform as well as the Optimax.

Depends on how you are going to use it. For heavy loads and watersports, you want more power. But I am an admitted power freak and I lean toward max available HP. I have had several "underpowered" boats and wished I had more power. I have NEVER wished for less power and never regretted spending more $$ for more power. I am not alone.

A 150 is plenty fast enough for a 20' boat, providing:

The engine is running properly
The engine is propped correctly
The boat is loaded properly

A 150 is about the standard for a 20' boat. I've had 3 different 20' boats and all of them had 150's and ran between 44 & 50 mph

Here is link to Boattest for a Robalo 207 w/Yamaha 150
It might give you an idea for what you can expect from a your Robalo202.

They are heavy boats. I have the R180 and going with the 150 vs the 115 was money well spent. Depends on what you plan on doing with it.

My dealer said it's a waste of money and the 150 is enough.

I had the same conversation with a dealer in Charleston this last weekend. He said the same citing a dealer demo. Sales rep said he had 7 grown men in the boat with no noticeable change in performance.

Not that I would ALWAYS TRUST the dealer.. In this case he's right.
200 would be overkill. 150 moves that boat close to 50mph with 6 people onboard.

What else would you expect him to say? Which one is in his inventory, and thus costing him money every day till he sells it?

The laws of physics says that this is impossible. You can't add ~1100 pound of load to a ~2600 pound boat and have no noticeable change in performance (grossly overpowered boats might be excepted here). Besides, if it were true, then the base engine would be a 115, the upgraded engine would be a 150, and the boat would be the steal of the century.....

My suggestion is based on a friends 19 ft. GW with a 150 HPDI. Power is adequate but nothing more. But if the 200 is a budget buster adequate is better than non existent.

As a former Robalo owner myself, I would always opt for the higher HP on those boats. They are heavy and have a pretty deep V for their size. I had an R227 with the 250 on it, and while 90% of their sales had the 200, I would've been very unhappy with the lower HP motor.
Get the 200 and don't look back.

Unless you were analyzing performance data would you really notice a few extra seconds to plane and a few less top end MPHs? I think his point was the $5k+ extra cost to purchase and mount the 200hp wouldn’t be justifiable.

where did you get this info? 50MPH no way.
Check out the Boattest results in my above post showing performance for a R207 which is a reasonable comparison to a R202 with a 150 Yamaha.

isnt a 150 made moving a 20 foot Robalo 50 mph. Boat has wood and very heavy.

The bulletin shows 42 WOT.


The 150 is enough if you don’t mind turning 4500 rpms to achieve 25 mph with a loaded boat.

Not sure what your saying here. At 4500RPMS I'm running in the mid 30's low 40's
Maybe the bulletin your reading is in KNOTS
