I finished the project and raised and tweaked the engines a bit. With 4 batteries and two people in the boat I was able to hit 27.8 mph. More than I expected. Now I have to mount my motor guide 24vlt motor and run the wires

Ive been out there on 3 days when summer storms popped up without much waring. All three times at least 1 boat sunk. I have also towed boat in as storms approached. Safety is key. A little extra speed helps as well

I purchased twin Suzuki 9.9 s for my boat last year. I can't say enough good things about the Suzuki. Elec start, fuel injected, power trim, and all for $2400.00. Another benifit of the Suzuki 9.9 is if you don't have enough power there are a couple of fixes. You can take out the breather restrictor plate and you now have a 15 HP engine, or swap the restrictor plate and the ECU and you have a true 20 HP engine. I just love my new Suzukis

I just received a pair of TH Marine Mini Jack plates. It will give 4 inches of lift and a 4 inch setback for each engine. Now my question is, How close together should i mount the engines? I currently have them at 24 inch centers. I'm thinking of bringing that down to 17 inches. Any thoughts? Thanks

Thanks Fin

Yea, I need to get the engines up a bit. About 3 inches. I just bit the bullet and ordered two TH Marine Mini Jack Plates. You can go up as high as 5 inches and it sets the motors back 4 inches. I'm pretty sure this will cure all my ills and give me a little extra speed. $150 for each bracket. now I just have to pull two engines and drill a bunch of new holes in my transom.

Thanks for the info. I will be trying a few things as soon as I can get the boat back in the water

I will look at my options. Short shaft is not one of them. maybe a hydrofoil may help

Yea they are 20 inch

Not a lot CR 9.9s out there

That may be the issue. I hade twin 15s on their in the past with no issues but they were older engines. I’ll have to look at my options. I don’t believe there is a way to raise them up higher. Fun project anyway

Yea, I’m pushing the spirit a bit. From an environmental standpoint I’m ahead of the game going from twin 15 hp 30 year old two strokes to twin 2021 four stroke. But the real issue is safety. The lake I fish blows up fast and at 8-10 mph your a sitting duck. They lose people in weather there almost every year. Also I need the extra power for fishing the Delaware river. Most of my fishing is in elec only lakes.

I just finished the bulk of the work on my 16 Sylvan Pro Select. NJ has HP restrictions on many of the lakes I fish. 9.9 Max. They don't seem to mind if I use more than one. For years I have been running Twin 1995 Evinrudes upgraded to 15 HP. What I did here is buy 2 2021 Suzuki 9.9 and upgraded them to 20 HP each. It was a very simple upgrade. I first used a single 9.9. on my 16 Sylvan I only had 7.5 MPH. I then upgraded it to a 20 HP. With single engine the speed went up to only 9.5 MPH. So, I bit the bullet and purchased a 2nd 9.9 and upgraded it to a 20 HP. What a Change. With the Twin 20 HP Suzuki outboards I now can hit 28 MPH. Wow, what a change. Still doing some tweaking to get things right. One issue I am having now is I get a large rooster tail between the engines. It is a problem. Lots of water shooting up and into the transom area. Plus I would think it is a large drag that may slow me down. I can't seem to find a reason for the Rooster tail. Any Suggestions? Regards Bryan

Looking for a 18-19 ft aluminum project boat. mid 90s to mid 2000s bad floor OK. needs to have good transom. Prefer Monark but others OK I am in NJ
