98 Speedster Engines

Getting ready to install the rebuilt 787 motors into the 98 speedster I picked up. How assembled can the engines be prior to dropping them In the hull? Also any tips and tricks I can take with me that will help would be appreciated. I do have the manual so that will help a ton in itself.

On my 95 speedster I installed the port engine first and had everything hooked up tuned pipe,carbs,oil lines ect.. Then I used a chery picker and hung it over enough to hook up the starter wires then lowered it down to the mounts. For me I tried to have as much Of they assembley process done on the bench to avoid climbing in the bilge and being in awkward positions. It also helps to have a buddy help you out with maneuvering the lift basically your only obstacle will be hooking up pos and neg starter wires wile it's hanging other than that it's pretty easy at least on my boat not sure how your setup will be though.

Definitely. That is what I'm looking for. I also don't want to be stuck upside down trying to connect things that I could have done on the bench prior. So we're both engines able to be maneuvered into the boat with tuned pipes and carbs on ? Or is it just the port side ?
 
With the portside I installed all lines the tuned pipe and carbs but not the flame arrester because the starboard tuned pipe won't fit into place with that in the way but I have 657x engines yours are prob a little different. Also before I installed the starboard I hooked the throttle and choke cable up along with the gas lines.Then I installed the starboard with the tuned pipe on but not the carbs just because I figured it would be difficult to hook the cables up because of limited space on the starboard side wall. On the starboard carbs I hooked the cables up before I bolted it down it just ended up being easer that way. If you use new oil lines you should leave them a little long so you can hook them up while the engine is dangling from the lift. All in all it's not that bad you just have to do a little planning. Before I put the starboard in I finished up everything I could on the port. Here are a few pics I dug up from my install.

For me, less is better. I would install the exhaust manifold and leave everything else off, including carbs. I think you're just going to beat your head against the wall by putting more on it, but that's me. That being said IF---IF you disconnect all the hoses from the boat and attached them to the engine it would probably be easier. It's still not all that bad, a few hours laying on the swim deck and your done. To each their own, you'll find what works best for you.
 
Two totally different approaches. I guess I will see when it comes down to it after I scavenge all the parts that I seem to be finding not included with the boat.
