Powering my T58 Turbine Powered Boat Project

1400 hp turbine engine

My T58-GE-8F Turbine

A very rare opportunity presented itself and as a result I now have a new T58-GE-8F motor for my project. All bright and shiny, this beauty has zero hours since depot level overhaul. That's right boys and girls; complete with paperwork and pretty little stickers on all the components. And (as if that were not enough) the T58-GE-8F is rated at a whopping 1400 HP output. The output ratings vary according to aircraft and the reporting agency; the T58-GE-8F is rated at 1,450 HP in the SH-2F Helo, rated at 1,350HP in the Kaman SH-2 Seasprite, and rated at 1,450HP in the SH-2F Seasprite

The T58 turbine engine powers the Sea King helicopter shown on the left in a hover during an Anti-Submarine Warfare (ASW) mission.

The T-58 turboshaft engine also powers the CH-46 shown on the right lifting cans of helicopter blades during an UNREP (Underway Replenishment) for the Navy fleet while underway at sea.

It looks a lot like a "jet shop" around here. Requiring only minor periodic maintenance, this T58-GE-8F is fresh from overhaul and won't need any attention for at least the next 2,500 hours.

We have T-58 & Rolls Royce Gnome gas turbines available to power your project.
We also have starters, manuals, instruments, and gearboxes for T-58 and Gnome gas turbine engines.

I mounted my T58-GE-8F motor on my test cart and brought it out of preservation. It starts right up and runs great- WOW, what a monster!

Next, I'll focus on converting my T58 for marine use. Among the many modifications, the exhaust will be turned 90 (pointing up) and a throttle linkage will be fabricated. I'll also need to work on the drive-train. I suspect it will likely be very similar to the drive-train Dino designed for his T58 powered boat project.

A little about Naval Aviation

Running my turbine engine brought back a lot of memories of my experiences in Naval Aviation. In particular, I recall those cold, rainy nights on 'The Rock' when we had to trim the J-52-P-408 engine on the EA-6B Prowler while standing right next to it out at 'high power'. Pretty noisy!

In Naval Aviation, there are three levels of maintenance; Organizational ('O' Level), Intermediate ('I' Level), and Depot (Overhaul). The squadrons ('O' Level) are where the aircraft are flown and maintained. Aircraft components are removed and sent to be repaired at I Level. Complete rework of entire aircraft, subassemblies or individual components is performed at Depot Level. I was fortunate enough to work in all three levels at various times over the course of my career. I enjoyed the challenge and found the work to be interesting as well as rewarding.

As a retired Senior Chief (Navy E-8), I applaud the dedication of our men and women currently serving in uniform around the globe in our Armed Forces. The Sailors on the left are preparing a J-52-P-408 aircraft engine for running in the test cell while deployed aboard the nuclear powered aircraft carrier USS Abraham Lincoln (CVN 72).

The Sailors on the right are performing an engine change on an EA-6B Prowler in the hangar bay while at sea aboard the USS Theodore Roosevelt (CVN 71). Try working under those yellow lights in an effort to meet the morning flight schedule. Been there, done that! I've got a wall full of awards and an 'alphabet soup' of designations including (AW/SW/MTS). Now it's someone else's turn.

Thanks to all those folks who have provided tips, technical advice, and information to help me with this project.
Soon I hope to be skimming across the waves at 120 miles an hour with a permanent grim etched on my face!
