I/O to Outboard Transition - The Good, Bad, Ugly

- Breathing life into an aged Inboard/Outboard with a ruined-hydro-locked engine. The challenges of replacing the transom in an I/O, reinforcing that transom, installing brackets, a proper outboard engine, wiring, rigging, creating ballasts, water testing...a JOURNEY!
When mine (1988 GM 4.3 V6) blew both head gaskets I did a top engine overhaul (my cost $800) and replaced the exhaust with a center riser conversion (my cost $1200) and it’s been running great for the 7 seasons since then…but I did consider the OB conversion but unless you’re buying used they are just too expensive to justify…
Thanks. I owned a 5.7 I/O in the past...I paid around $3.5K for aftermarket risers and manifolds and did the job myself. I was told it was a 3.5-year regular replacement due the saltwater's deterioration inside the cast units. You are correct...you can buy a refurbished Mercruiser engine for less money than an outboard, especially if you're doing the work yourself.... and then the money spent on a bracket and beefing-up the old I/O transom for the transition...it's expensive. I won't do it again. I'm ready and willing to refurbish an old outboard and keep it an outboard but an I/O to Outboard, especially with a transom rebuild, is just NOT worth the money IMHO. Thanks for watching...you made the right decision.

My conversion cost a bit more because I had to buy some VP parts to make it work on my old OMC. The price for just the manifolds & elbows was $750 (Barr Marine aftermarket)….
@@Luigi-pk8mk I purchased my manifolds and risers from "Barr" as well...pleased with the fit, finish, quality, for aftermarket...still expensive for an old retiree.
How did the sea trial go. Cruise and wot
Hello Rich, thus far the "sea trial" has been terrible. Initially, I ran into a trim sender problem and the defaults that result from that...limp mode and power interruption as per Vessel View. Corrected those defaults here: th-cam.com/video/1MTcvWxHzRI/w-d-xo.html Second sea trial, the engine began missing at 2750 RPM...I believe it's a fuel starvation problem, I've ordered a new fuel tank pick up and I'm doing away with the anti-siphoning valve at the fuel tank hoping that will cure the problem...these are probably OEM and partially obstructed. Thus far, 9-MPH is max speed. Changing prop pitch - experimenting. The vessel handles very well, takes chop well...if I can work out the performance problems, she will be a great near-offshore vessel.
Some ugly welds on that bracket from Viking
I would have constructed my own bracket but my welding experience is limited to carbon steel - oil-field pipe...my favorite...would enjoy toying with aluminum welds...want to build a permanent cover-hard top for the boat. Thanks for your input.
Nice job dude, but way over built. Also next video try not to whisper as much 😂😂😂😂
Thanks Richard. I've always been one to "overdo" projects. Sometimes that "whispering" was related to dehydration...I lost between 12-15 pounds over the span of this project, 1-kidney stone passed and 1-UTI in the Florida summer heat/humidity. Definitely, a learning experience. Thanks for watching.
