That’s a timely article. It sure sounds like cavitation is a major issue in reading that. Their idea of getting custom propellers made may be the way to go, I believe the propellers for the G2 Evinrudes are specific to those engines, not a lot of aftermarket options.

..... oh yeah Biggd ...... with that new propeller that's just right for powering up The Dive ....... that there barge there ..... will be gett'n up on plane just so fast ..... it will be able to pull two water skiers right off from sitt'n on that Flightcraft dock without them gett'n their knees wet ..... new propellers is all it needs to make everything go good!

..... 2019 will be the year for The Dive!


....you gotta admit ...... putt'n a huge red sail, mast and boom on the barge could make it a way cool sailboat.
……………..

Will be interesting to see what some different propellers do for moving The Dive around the lake, and if two-strokers have enough torque to make it work out good?

You know the US Coast Guard seems to have settled with using the 250-hp Honda, two or more per boat, for powering up their 35' something patrol boats. After trying all the different outboards, the Coasties go with Honda because they just need an engine that works good.

Seems like a Honda 4-stroker would have more torque with its' intake-compression-combustion-exhaust 4-cycles than an Evinrude 2-stroker with it's abbreviated, higher rpm, intake & compression - combustion & exhaust, 2-cycles?

Like, who knows ……. but maybe just maybe, Honda actually makes a 250 designed with an extra heavy gear case, a slower engine speed, and a larger propeller that is designed for pushing those slower, heavy, high water resistance loads ….. and it's named the Honda 250-b, with the b an abbreviation for barge …… like, who knows?

Today’s Laconia Sun has a good write up about the Dive, it also goes into more detail about the engine troubles they encountered on the high seas of Lake Winnipesaukee!

Most likely they will have to replace the lower "foot" of the outboards... that will allow them to essentially regear the motors and allow them to swing a much larger diameter propeller slowly... giving them more control and better thrust.

the little 14" diameter props on those outboards will def not cut it...

I thought that their engine problem was "solved".

From their FB page on August 18th.

"The Dive
August 18 ·
We ARE coming out to Smalls Cove!!!! Save us "our" spot please! Engine problem solved 🤞 see y'all soon! "

As an alternative approach to the water pick up issue, could forward facing scoops be afixed over the standard inlets?

Why not have a jet ski that can bring customers to the boat?

He is talking about cooling water to the motors. You seem to be talking about getting patrons to the boat. An entirely different issue.

Default .... but just no good?

So's, how come semi-tractors pulling a 53' van trailer with a gross vehicle weight of up to 40-tons always have a diesel 4-stroke engine as opposed to a gasoline 2-stroke engine?

Like, what the h was they thinking when they went and got two Evinrude 2-strokes, which are actually very, very expensive ...... but just no good for pushing along a huge, heavy barge like The Dive?

For many years until recently the Detroit Diesel was a 2 stroke that made plenty of power. The 6V71, 8V71, and 8V92 were 2 strokes used to power many trucks, boats, and a lot of fire apparatus. Many fire trucks and boats still use them. They fell out of favor with over the road trucks because of tighter emission restrictions.

The Evinrude Etec is a very good outboard. It has an auto winterization feature fogs the engines itself in minutes, with no trip to the dealer.

An Evinrude E-TEC engine does not require belts, camshafts or exhaust valves, which means there are fewer parts to wear down or malfunction than a four--stroke outboard.

I have owned them in the past and found the Etec to be quiet and smooth and almost maintenance free.

Default .... get the message?

Oh well ….. what with the big, big, high cost of a new 250hp outboard …. seems very likely The Dive will cross their arms and legs, cross all their fingers and toes ….and hope to high heaven …. their Evinrude E-Tec 250's be will good enough to get it moving good with two new and different propellers installed to replace what they have …. just got to give it a trial run ….. and think positive Evinrude thoughts!


Evinrude, Yes! …… Honda, No! ….. Evinrude, Yes! ….. Honda, No! ….. Evinrude, Yes! ….. Honda, No! ........ etcetera, etcetera, etcetera ….. and just a-keepa think'n this …… Evinrude, Yes! ….. Honda, No! …… get the message!


And, if the Evinrudes make the high heat buzzer sound up, what with the new props ..... or, they just don't cut it or something ..... there's always that 'Cash for Clunkers' program with the federal EPA .... just what got the Mount Washington their two new caterpillar diesels, back in 2009, worth $750,000 .... to replace their old 1940's diesels that made an iconic "wush-wush-wush" sound about two minutes ahead of the Mount coming around the bend ..... that "wush-wush-wush" done been replaced by an efficient but non-iconic bzzzzzzzzzzzzzzzzzzzzzz sound.

I am certain that someone can find the link but the Dive will be stationed at the Weirs for 2019. Check Facebook.

Looks like the Dive is being copied in Boston Harbor.

Tried to open my Dive App today …………. (curious if there was any info of their new Home port)


got a pop-up saying ……... "app is no longer active"


Did the Dive drop the App????

Was Just on their facebook page, where they have announced that they will be opening on May 10th at the Winnipesaukee Pier....

Should make for an interesting summer to see how often the now venture out...
