I got my HB professional tunnel with the 60R propped with the Mercury spitfire xp 14p (its not the correct prop IMHO) this past weekend. I ran it for about 3 hours (its cold here in Texas). I know a lot of people were wondering about the performance, What questions do you have? Hopefully be able to answer some of them. Jacked up on 6 water pressure was a solid 18-20 psi. I just need to learn how to drive it, we we running in about 6" soft mud bottom in a back pond and needed to turn around, started turning and rear end got light and lost momentum. She still floated.

Pretty bitchin

Your prop blew out on the turn. Go see Tran Sport for a cav plate and Jack Foreman for a prop.

It looks badass though!

That's the way to break her in! Looks sweet

Who took that picture?

Who took that picture?

I did. LOL Left the push pole at the house.( amateur move)
On another note, the skiff did well in extremely shallow water. Made it a few hundred yards across a shallow firm mud flat. I don't know how deep it was but 4" would be my best guess, because I didn't stop. LOL Video is on my Facebook page.

Have not aired it out yet, but 5500rpms was seeing 33mph on GPS.

Question. Do I have to wipe my feet before boarding ?

Need a prop with cupping. Will prevent cavitation without the need for a cav plate. IMO, if you need a cav plate, motor is setup wrong or prop is wrong

Also... congrats on the rig!!!

100% agree. Going to have one made. the Spitfire has zero cup.

Get a Jack Foreman prop (3blade and water scoops) then call Transnoats and get there cavitation plate. You’ll probably be able to lift your motor up too the bottom holes. I did those modifications on my maverick tunnel and it made a huge improvement. Great looking boat even muddy.

running a skinny flat.

Ahhh skiff porn!🤤

Congrats on the new engine. I thought about one but went in another direction. Will still be waiting several months but my current Merc is running fine.

The top end will increase once it's fully broke in. I'm turning 6000 at WOT with EFI 60 and 4-blade Trophy Sport prop.

Which model of Bob's jack plate do you have? Standard 4" Ultra Light?

I believe its the ultra light 4"

Rob, that motor has a pretty big gear case ratio similar to the Suzuki. You can swing a pretty big prop. For example, the prop on my Zuke is big enough that I had to grind the steering anti-torque tab off to clear the prop blades. Cup added will help give the prop some bite when running at high jack settings, especially in a tunnel where the water is a little more turbulent then water coming off the back of a non-tunnel boat. The bigger blades will give better hole shot and also help stay hooked up when running at high jack settings. I'm running at full jack up on my X all the time except when motoring around the boat dock. I'm getting really good shallow water performance with my Foreman prop (12.5"D - 14p 3 blade) so your tunnel Pro should really be able to do silly shallow once dialed in.

@jay.bush1434 we need to go run around and take pictures. I've a camera too.
