How the eLogbook and Marine Diesel Basics 1 saved the day!
Free Manuals are Amazing
I’m currently installing a low hours Yanmar 3GMF in my boat to replace the venerable 2QM20 that served me well for over 20 years. Finding manuals was a complete nuisance until I came across Denison’s site. All the manuals I needed in one place, easily downloadable, and FREE!
Why is that a big deal? Because every other site wants you to pay, and their product isn’t cheap either. With Denison’s downloads, I know I’m getting the real deal, not some poorly scanned copy that might or might not be correct or complete.
I am AMAZED!!!
I am a 64 yr old newbie to learning marine diesel mechanics for taking care of the sailboat. So many people said I’d never learn. It was a struggle until this showed up on Kindle. What a God-send. I only wish the Troubleshooting guide was available to add to my library.
Highly recommend this for ALL boat owners (that is, ones with engines!😇)
Response from MARINE DIESEL BASICS
Many thanks for your generous review. I’m delighted that the book has demystified your engine for you and helped you to learn and to get more comfortable. I’m working on book 2 at the moment – 400 pages on How Things Work and Installation Guidelines – and expect to publish later this year. Troubleshooting will be book 3 and I’ll start work on that book as soon as I can. Again, thank you.
Best buy!
Well structured, informative layout & content. Gave me the confidence to make a “working relationship” with my engine at last – Thank you!
Response from MARINE DIESEL BASICS
Thank you for your kind words. Getting over that initial trepidation and engaging with the diesel system is what the book – and the Marine Diesel Basics series – is all about. Much more to come.
Great book, well worth the purchase.
Easy-to-follow, ordered and informative drawings. Full coverage; learnt about a detail (heat exchanger anode) that was not mentioned during a 12-week intensive sailing course. Looking forward to books 2 and 3
Brilliant
Fantastic book and logbook. I am a diesel virgin and when diesel died in a force 7 and trying to get to a safe harbour I reached for this book to walk me through the problems I find it easier to read and follow I do not need velocity numbers or oil efficiency or how to re build my engine upside down blindfolded I need simply problem solving and easy to follow instructions and this is the book for me . I also have calders book but I would be at the bottom of the ocean trying to find the info I needed in time. the log book is also great. I I can’t even read my hand writing so this is a great help and I can enter and follow maintenance over the year

Thank you for your generous review – I’m delighted you found help in the book in a challenging situation and admire your determination. Troubleshooting information will come in detail in book 3 in the series. At the moment I’d mid-way through creating the drawings for the 400-page book 2 – How Things Work and Installation Guidelines. Thank you for taking the time to write and share your review. Fair winds and a reliable diesel!
