1990 supra sunsport

[Konakev]

Recently purchased. It's a little bit if a project but it runs, and the gelcoat seems ok. No wood rot that I can find yet. Will need help with locating the impeller and replacing. Anyone know where I can get quality Reman'd engines?https://uploads.tapatalk-cdn.com/20200310/8dddd1cb48b2eb22d86d3e8c8c814a25.jpghttps://uploads.tapatalk-cdn.com/20200310/36c1e1fa1a86d0015fdeda7b80daae01.jpghttps://uploads.tapatalk-cdn.com/20200310/305b89ebbf6e41b3aae38bac9f04cf76.jpg

That is a 454 GM engine. Why do you need to replace it? Are you sure its a Sunsport? Most Sunsports have a 351w.

I guess I really didnt look at the pink slip all that close...that's what it was being sold as... what are the differences between sunsport and others? I'm not super familiar with these supra boats

But I just wanted to know a general idea if this motor turns out to be badd. I don't have much experience rebuilding Small or big block Engines. I'm trying to get more knowledge on this motor so I can look up parts to replace i.e. Impeller Water pump spark plugs Carb rebuild your know the usual

A Sunsport with a 454 is a rare boat. Special order item. That is nice. I have a 351W if you want to trade. :)

After doing some more research I kind of worry about the condition of the stringers. I did not Inspect before I bought it. But the floor is solid and no soft spots that I have found yet.The engine compartment and engine day look pretty clean and no signs of rot in bear yet. It would be awesome if the stringers have been repaired or replaced already

CORRECT ME IF IM WRONG. Isnt pleasure craft a ford engine? Do they still use a GM block? Engine code is PLN-WR-L10 which I assume is a ford 7.4 ford. Upon some research I found this gem. So I'll have to do more research when I get home. But what kind of raw-water pump does it use? Sherwood? Johnson? Does it really matter what kind I put on there? As long as its pumping h20 I dont see why it needs to be mounted underneath the engine where only miniature oompa-loompas can get to... lolhttps://uploads.tapatalk-cdn.com/20200310/a2a36bbed3d4ff7f53aad93a7c2b2275.jpg

NVM I just read where it says "454 is a gm block" but it still doesnt answer what type of pump it is... are their dif styles? Can i replace with a dif style if it's cheaper?

Dash help! (Sorry I am taking over the discussion feed) my dash has the old style push-on-push-off switches and I was wondering what others have done to their dashes... this style looks pretty dated and the switches occasionally dont work. Time for a new dash... anyone have any ideas? Recommendations to update the helm look/function?

You can get new push button dash switches from Skidim . Supra wiring is a birds nest at best I would not want to try to change for different style switches. Somebody has already been in there the silver plates were black originally

Somebody has already been in there the silver plates were black originallyThanks for the heads up! Can anyone tell me exactly what all the buttons are for? I've only learned about the ignition, and the bilge... any help would be awesome. (Post pics of your dash if possible) thanks again ppl! I'm grateful for the help.

They are actually circuit breakers . They will pop if something goes wrong with the circuit. You can also use them for a switch if you push down on them. They do go bad after years skidim keeps them in stock.

I want to label them nicely and maybe get real labels made for them. Just not sure what they all are... thanks
