Got the new xr6 150 broke in on the 20 HDSC. I am running a cheap Michigan Wheel 13.75x21 dog eared 3 blade prop that came with the rebuild. I have a six inch jackplate I ran it up to WOT and...

I am upgrading my HD 20 to a 150 merc. My data plate says max 140 hp. Express says that if I get Baystar steering or above and then take it to Xpress dealer who is willing to vouch for me. The...

I could not agree with Buddy anymore. My dealer talked me into a 2 stroke 90 Merc on my brand new HD 20 in 2007 which is a slower hull design than your H. I guess he had a surplus of these and...

Thanks. Good info. That is the way I am leaning with either the Power tech 4 blade bow lift or the mercury 4 blade trophy. I was just hoping to get some guys with HDs that have been thru this...

Thanks. Yeah I am going with either the Tempest or a Power Tech TR04 in either a 21 or 23 for my high perfromance prop but I have a choice of cheap aluminum props for my starter/spare prop. This...

Gentlemen-

I have some sales men telling me I need a sternlifting (semi cleaver) prop like the Powertech SCE3 while others are specing out bowlifting like the Tempest and trophy and TR3 and 4...

Hey Spanky. I have a few choices for an aluminum starter/spare prop. Which do you prefer? 14.5x19, 13.75x21, 15x19, 13x19? Thanks. I did the Mercury Prop Selector and it said to go with Black...

What diameter should this Tempest be? I am hitting a local used prop shop to purchase a cheap used aluminum that I can use initially as a test prop so I can get some baseline numbers to help with...

I am upgrading my 20HDSC from a carbed Merc 90 2 stroke to a rebuilt 2001 Merc 150 xr6 carbed 2 stroke. The new motor is coming without a prop so I am looking for suggestions. I have a 6 inch cmc...

I agree but I was hoping for specifics like actual MPH and depth of draft from actual hd20 owners. Any HDers listening?

What did you do specifically to rid the mess under the console? One of my biggest complaints on my 07 hd20sc was the shotty wiring. Whole bunch of cheap in line fuses and black tape and flimsy...

Hey Rooster what kind of performance do you get with your 150 on the hd20. Do you have hydraulic steering and what does your coast guard sticker say for max hp?

I currently run a carb 90 hp Merc on my hd20sc. I am able to get a top speed of 42 mph with a tuned prop and jackplate. Most people tell me that is great, however, the holeshot and top speed with a...

Thanks for the input. Unfortunately conditions were calm at the time of the pics.

Anyone else out there with a 798 on a HD20. If so what are your experiences?

Long time reader first time poster. I am praying you guys can help. I have been working with several other people on a couple of different forums for about a month now trying to trouble shoot my...
