No, not front to back. but back to back threw coupling that will joint at a reduction gear; using clockwise and counterclockwise rotation engines. So that one or two engines can run the shaft by throwing levers on a clutch coupler. there are cases of blocks and cranks being bolted together but they have a problem with "Critical Speed" that is when the harmonics of the engine and the harmonics of the boat/ship match. This causes a catastrophic vibration that can shear the nose off the crankshaft at the vibration dampener --they work best when they get to maintain a constant speed and the propeller pitch is changed for different speeds. The main problem is the governor set up so that each engine takes the load equally--or one engine will try push or drag down the other. Tractor pulling is done at full power and no attempt to hold a cruising speed---big difference between running for days straight and a 30 sec pull. I would not recommend a multi engine set up unless you have a extra person to sit in the engine room and make corrections to the likages, governers, and to watch the load/ exhaust temps and rail pressure. Are you looking for more power or more speed?. If you can go the max. engine rpms with 200 hp at 2700 rpm. Having a engine going the max rpms with 800 hp at 2700 rpms is not doing you any good. Your propeller is still only turning at 2700. Your problem may be solved with a differnt speed drive unit, different pitch props, or an engine that turns a higher rpm--as in an engine that turns 3500 rpms. Then of course you may need more horsepower to push the boat. First you need to know what you are looking for power or speed.
when you hear people talking about boats what is GRP or something like that?
i think you technically could via input via viscous coupling, but it would be a difficult and expensive.

How do you make a paper boat?
Its done by Detroit Diesel for many years and some of the very early chrystlers and GMs did it for the V-16 engine. But, don't waste your time trying. For a smaller boat like a shrimp boat size, get a cummins QSL,QSX or ISX. A butt load of power for the size and weight of the engine...money well spent. Much lighter and still better HP to weight ratio and less pricey than doing a tandem hook-up. AND MORE FUEL EFFICIENT! I've worked on a lot of marine aps. I can go on and on with resasons not to do a tandem. Besides...look at what the size and weight of that beast would be when you get done! LOL
Where on the Internet can I find a copy of a Coast Guard report regarding a specific rescue?
It can be done. Just look at the competition sled pulling tractors. A lot of them do it.
Anyone have trouble with Bayliner Boats?
It is done very often in tractor pulling..They have to be syncronized..
How can i get a job in the Sonatrach Petrolium Company marine branch?
sure can, one behind each other, the most I've seen is 4 V8's in a row the tractor pulling sleds some of them have 4-8 V8 engines. even beside each other. depends what you want to do! anything is possible.
do any submarines have screen doors?
have you seen the tractor pulls it's great and hard to put two together look up tractor pulls on google.com
how can i convert a car diesel engine to use in submarine?
Sure can, and is done often, Detroit Diesels are made to hook up in line to one another if need be.
stacker reclaimer?
I don't think so. The prop in front would cause a vortex. (An air pocket) That would make the aft prop over-rev.
I have a 92 Bayliner Trophy , fish tanks constantly fill up with rain or deck water. Covers -gaskets?
no to much stress and youll throw rods like u would never believe
