I have run across a freshwater use Johnson 48 SPL, oldish but in nice shape. Might be inexpensive power for a friends 13' Supersport, full transom. A couple questions before I try to buy it.

Is this J48 too much power to get the boat insured? 40hp is tops,? If the horsepower is ok, then, are there any reasons that the engine would not bolt onto a 13' Supersport?

Thanks David

Why don't you ask your insurance agent? How much does it weigh--that would be my main concern. If I still owned a 13 and I could repower with any engine, I'd choose the 203 pound Honda 50, even though it is not EFI.

48 weighs the same as a biggie. Seen many on the water. Ask insurance agent.

David, I work for State Farm. We don't check horsepower ratings as far as I know. Another company might be more specific, but unless they are boat oriented I doubt it.

I currently have 5 boats insured with State Farm and they require, among other, the following data: Max hp rating, engine hp, engine serial # ... blah, blah, blah.. what they do with this info I don't know but they know up front whether overpowered or not... also they require photos of the boat...etc...etc...etc... my only concern is liability (I can afford to loose a boat but can't afford a multi-million lawsuit for some accident) since we live in such a litigeous (sp?) society. My insurance company may insure if overpowered but may loose a case to a good prosecuter... some thoughts! Happy and safe Whalin'... Clark... SCN

KeysNole- Slight change of topic. My 22'OR '86 with an oldish 225 Johnson has been insured for several years with State Farm. My friends '89 22'OR with a 200 Johnson same vintage is also insured by State Farm. I'm told that the approx $50 more per 6 months that I pay is due to the fact that I'm getting close to the max on a 22'OR w/o WD. The boats and the owners are AOK, not nut cases. So what gives?? Thanks David

Sounds like a bunch of cow popy to me. The difference between a 200 $ 225 should not amount to $100/yr, especially when his is newer. My insurance company basically insures against agreed value. The boat is "rated" so if we both had 1989 22 OR's with a 200 & 225 and lived in the same town, etc the premium should be the same if we both had agreed values of say $18,000.

Well I bought the 48 spl. Mid 80's vintage. Only used in Central Fl fresh water lakes. Runs like a top. Came with an oldish but viable trailer plus a bummed out 14'10" Palmetto bowrider. I paid $700. Biggs, what's your opinion of the price -- a loser or a winner.??? David

Great price....actually late 80's I believe they started the SPL line in 87. Run the model # at They have a reference section.

Thanks Biggs. Thought so, but wanted to confirm. By friend is readying his 13'SS for the 48spl-thrilled. Gave the 14'10" Palmetto to my plumber and friends- they're going to make a flats boat out of it. Thanks again. David

Gentlemen-- A couple of questions, please help.

1) What diameter and pitch prop provides the best day to day performance from a J48SPL on a 13' SuperSport?


2) We may be able to pick up a beefy jackplate for a song. What are the pro's and con's to putting the J48SPL on a jackplate on a 13' SuperSport?

Appreciate your input as these 13'ers are new to me. Fine boats. My friend is R/R ing the entire wood interior as we speak. Thanks for your input. David

I would start with a 17". I ran a 17" on my 15' but had no tach.
