Johnson 10hp SeaHorse QD21, Serial #2016649. Unit was kept in garage but not run for a few years. Tank that came with it is a rust bucket (in garbage). Will search local craigslist or flea market for tank. I live in Allentown, 60 miles north of Philadelphia.

I still think that you weren't running that old boat correctly. A 20hp motor with two people, gas, and batteries in a boat is going to struggle to get onto plane. At 1/2 throttle you were likely in that point below getting on plane where the transom is closest to the water. You should have trimmed in all of the way and gone full throttle before buying a new boat. From everything described that seemed to be the problem. I've got an old 12ft Starcraft that's probably only rated for a 10hp and have had three 200lbers in there fishing with my old 5hp motor. It's never been close to taking on water because that 5hp can't raise the bow. A bigger motor would have gotten it there.

Sooo.. how come you don't take your new 20hp unit and put it on the new 16' rated at 890. Then throw the old seahorse on the 14' and sell and recoup some money?? in the Early 90's I had 14" aluminum with a 20hp merc and it was a rocket with 2 people in it. Great boat for fishing the lakes of the canadian shied. Slayed ALOT of fish.

20hp already on the 16', will get out next few days. Have to get the Johnson running or at least do a compression check before I decide weather to package or sell motor buy itself. A bunch of local PA lakes only allow electric, so keeping the 14' is an option, after all doesnt everyone need two boats.

Fellas -- just found this thread while researching a similar problem. I have a Grizzly 1648, had been running a 9.9 and just upgraded to a 15 4-stroke so about 25 pounds heavier motor. Usual load is trolling motor on the bow, 2x batteries just behind the raised casting deck, gear distributed evenly on the floor, me + gas tank + battery back in the stern area. When running at half-throttle during break-in I noticed spray coming off both sides of the motor shaft, spray directed up and out (not back away from the boat, but outwards so the spray is more or less parallel to the transom) and rising about as high as the top of the transom. When running 3/4 throttle the spray actually comes in over the top of the transom and it's enough water coming in that it's not trivial. 20-inch transom and 20-inch shaft. I had the outboard set in the second of the six trim positions, with one being the farthest down position and six being farthest up. Reading the comments above it sounds like I need to trim the motor all the way down closest to the transom? And just continue past 3/4 until the boat gets on plane?

Welcome to iboats.

Please start a new thread of your own. Only the original poster is permitted to resurrect threads older than 6 months. I'm sure one of the moderators will be along to confirm that.

Don't need to, JoLin. You got it. :thumb: Jobu88 has started a thread and is getting advice.
